Installation of pyearth with python 3.8.10

[pgr123]

Good evening
I tried to install pyearth with pip3 install sklearn-contrib-py-earth but I got errors.
I have installed sklearn with pip3 install -U scikit-learn without problem.
What can I do ? How can I install pyearth on python 3.8 ?
Thank you to help me.
Excuse my bad english (I am french).

@pgr123 Have you tried building it directly from source? I always have good luck with that. Assuming you are using anaconda in the default location, it would be:

git clone -b issue191 https://github.com/jcrudy/py-earth.git
cd py-earth && ${HOME}/anaconda3/bin/python setup.py -q install --cythonize
rm -Rf ${HOME}/anaconda3/bin/pyearth && mv pyearth ${HOME}/anaconda3/bin/

This project is largely abandoned, and the pip release is out of date. There is a branch here that seems to work for most folks:
#210 (comment)

Are there any reasons for it being abandoned other than time cost to update the package?

[kevin-dietz]

@jhogg11 The main author has largely abandoned the project. However, there is nothing to stop someone from forking the repo and taking up the reins

[pgr123]

Thank you for your responses.
I know the "pip install git+https://github.com/scikit-learn-contrib/[email protected]". It worked with Python 3.8 but it does not work with Python 3.10 (and then with the new Ubuntu 22.04). I don't know why !

[kevin-dietz]

@pgr123 Haven't tried it on 3.10 but I can confirm it does work on 3.9. If you want to try it on 3.10, the following code may work for you:

git clone https://github.com/jcrudy/py-earth.git
cd py-earth  
python setup.py build_ext --inplace --cythonize
mv pyearth path/to/site-packages/python3.9/site-packages

cd py-earth  
python setup.py build_ext --inplace --cythonize
mv pyearth path/to/site-packages/python3.9/site-packages

I'm also using 3.9 and this works for me. Thank you!

[pgr123]

Thank you but that does not work.
I got many errors like :
error: ‘PyThreadState’ {aka ‘struct _ts’} has no member named ‘exc_value’; did you mean ‘curexc_value’?
error: ‘PyThreadState’ {aka ‘struct _ts’} has no member named ‘exc_type’; did you mean ‘curexc_type’?
error: ‘PyThreadState’ {aka ‘struct _ts’} has no member named ‘exc_traceback’; did you mean ‘curexc_traceback’?

and at the end I got :
error: Command "x86_64-linux-gnu-gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I/usr/lib/python3/dist-packages/numpy/core/include -I/usr/include/python3.10 -c pyearth/_util.c -o build/temp.linux-x86_64-3.10/pyearth/_util.o" failed with exit status 1

Do you think there is a solution ?
Have a good day.

[kevin-dietz]

@pgr123 the project has been abandoned so if you are dead set on using py-earth then my suggestion would be to use python 3.8 or 3.9

[pgr123]

It's a pity !
So, there is no mean to uses MARS (earth) with Python ?
And else, how can I downgrade to Python 3.9 ?
Thank you.

[pgr123]

The problem seems to be with Python 3.10.
I installed Python 3.9 but when I try
python3.9 -m pip install git+https://github.com/scikit-learn-contrib/[email protected]"
I get an error : No module named distutils.cmd
I don't know what to do ! That new version of Ubuntu with python 3.10 (bugged) is very difficult and for me, it seems unusable and take me a lot of time.
So I think there is for me only one solution : go back to Ubuntu 20.04 which works perfectly !!!!
Thank you but that new version is not usable, I'll wait the version 22.04.5 or 22.04.6 !!!!!!!

[pgr123]

Even Spyder does not work with Ubuntu 22.04.1 and Python 3.10 !

@pgr123 Haven't tried it on 3.10 but I can confirm it does work on 3.9. If you want to try it on 3.10, the following code may work for you:

git clone https://github.com/jcrudy/py-earth.git
cd py-earth  
python setup.py build_ext --inplace --cythonize
mv pyearth path/to/site-packages/python3.9/site-packages

does this work when I'm installing pyEarth on a virtual environment? (i.e a Django environment)

[pgr123]

How can I install py-earth on a virtual environment ? I never used virtual environment and I don't know what Django is.
Thank you.
Have a good day.

[pgr123]

The update to Spyder 5.4.0 works with Ubuntu 22.04.1 and Python 3.10.6 but I have actually no solution for py-earth.
Someone know how to do a earth model ( MARS : Multivariate Adaptive Regression Splines) with Python under Python 3.10 ?
Thank you.

[kevin-dietz]

@vea-therese it installs fine using pipenv, so I see no reason why it wouldn’t install in other virtual environment setups

[vea-therese]

@vea-therese it installs fine using pipenv, so I see no reason why it wouldn’t install in other virtual environment setups

I've tried pip install and cloning but it still won't work. Though I haven't tried downgrading my python version, I currently have 3.10

[kevin-dietz]

@vea-therese Others have mentioned it won’t install properly on 3.10 but should install fine on <= 3.9

[pgr123]

That is true but how can I change the Python 3.10 do downgrade to Python 3.9. And I must reinstall all my python packages and the problem is that Ubuntu 22.04.1 use Python 3.10.6 so it is used by the OS and I cannot change it. What can I do ?
Thank you.

[vea-therese]

@vea-therese Others have mentioned it won’t install properly on 3.10 but should install fine on <= 3.9

I downgraded my global python to 3.7, it still didn't work. I tried 3.7 because I was able to install pyearth in a conda environment with a 3.7 python weeks ago. That's why I'm wondering if it is possible to connect a virtual environment or the Django project into my conda environment with pyearth.

Thank you.

if you're using conda, I just typed: conda install python=3.7 or 3.9 since that's the version that you prefer.

Though if you're referring to the global python, I just uninstalled the 3.10 and installed 3.7. I use Windows, I'm not familiar with Ubuntu.

[pgr123]

Thank you, I don't use conda.
Maybe, I must install it (or anaconda) but I don't know how install and use it on Ubuntu.
And is it sure that py-earth will work with it ?
Seen the big changes in Python 3.10, I think it should have been called Python 4 (LOL !)

@vea-therese Here is a code snippet to try to install it in a virtual environment.

git clone https://github.com/jcrudy/py-earth.git
cd py-earth  

pipenv run $(pipenv --venv)/bin/python setup.py build_ext --inplace --cythonize

mv pyearth $(pipenv --venv)/lib/python3.9/site-packages

If that doesn't work, this docker image may help you install py-earth into a virtual environment: https://gitlab.com/gitlab-data/data-science

[pgr123]

Thank you, I'll try that tomorrow.

[vea-therese]

I forgot to thank u @kevin-dietz it worked! We're now presenting our thesis.

[pgr123]

Good morning,
I managed to compile py-earth with Python 3.10.
After
git clone https://github.com/jcrudy/py-earth.git
cd py-earth
and we must modify the files utils.c and types.c and changes the "exc_" with "curexc_".
Then the compilation works and the packages works in Python 3.10 !!!! Good news ! And no need of virtual environment !
Thanks to all. Have a good day.

Thank you! Just an addition, I had to replace "exc_" with "curexc_" for the other .c files as well and using python setup.py install --cythonize

@kevin-dietz the analytics image in your repo seems based on Python 3.7. What is the minor version of 3.9 or cython version you have to make it work? I could not compile on Linux based system. Thanks.

[kevin-dietz]

@vancities we have stopped supporting py-earth in our image because the package has not been updated in 5.5 years.

[pgr123]

I succeeded in running py-earth with Python 3.10 with few modifs and it works well !
If somebody want to know how to do, tell me.
Excuse my bad English.

[Williamz4lyf]

Hi, how did you do this?

[pgr123]

Hi Williamz4lyf,
You must change something in the sources, so :
git clone https://github.com/jcrudy/py-earth.git
cd py-earth
then you must replace all the "exc_" with "curexc_" in the files _utils.c and _types.c
and compile with
python setup.py build_ext --inplace --cythonize
and then move the obtained (corrected) directory pyearth to your directory /lib/python3/dist-packages with
mv pyearth /lib/python3/dist-packages
and this is all !
If you want I can send the corrected directory pyearth.
Have a good day.

Hi pgr123, could you share which numpy and cython version do you use? If you could share correctred directory, it would be wonderful. @evertonsantanaj mentioned that there are more .c files needed to be changed.

[pgr123]

Hi vancities, I use numpy 1.23.3 and cython 0.29.14.
(Yes you must change all the exc_ in all the c files.)
Here my modified compiled directory pyearth. You have just to unzip and copy it in /lib/python3/dist-packages :
pyearth.zip
(I use Linux Ubuntu 22.04 and Mint 21.1)
Excuse my bad english.

[vancities]

Hi @pgr123,

Thanks for your reply and sharing. Do you happen to still have the files that before compilation(the repo you made modification before running python setup.py build_ext --inplace --cythonize)? It would be helpful for people to compile with the modified files on different platforms. Btw, I assume your base files are from master branch instead of the more recent 0.2dev branch?

[gb07bh]

@pgr123 It would be helpful if you could just zip the modified files, as stated by @vancities .

[pgr123]

Here is the corrected version of the modified files for pYTHON 3.10. I hope that help.
pyearth modified files.zip

[gb07bh]

Thank you very much @pgr123 !

[pgr123]

With pleasure !
Have a good day.

[twistfire]

@pgr123 can you help me to resolve the issue I have with installing this package?
It seems that my Cython or something is wrong. I did exactly like you described. in my virtualenvironment installed numpy and Cython using pip, python 3.10.6.
cloned the repository

git clone https://github.com/jcrudy/py-earth.git

replaced files with modified versions you have provided in pyearth.zip..

But then, it can't compilate files using Cython?
Can you help to resolve that issue?

The problem is that pyearth does not work with the new new versions of numpy and scipy so what I have do is to install the good versions with
pip3 install numpy==1.21.5 & pip3 install scipy==1.10.1
and then pyearth works.
Otherwise, you must use earth with R by means of rpy2 but you must know a little R to do that.
I am sorry but with numpy==1.21.5 and scipy==1.10.1 pyearth works fine.
Have a good day.
Best regards.

Yes, surely, but you don't need to recompile the sources. You have just to copy the directory pyearth of my zip in /usr/lib/python3/dist-packages if you use Linux. On windows, you must search where is the directory dist-packages for python3 and copy here. I don't use Windows so I do not know where it is.
If you don't find my directory pyearth in my zip, I can resend it.
See my comment on May 2.

I use now Python 3.10 and my version of pyearth works well.

[twistfire]

I use Ubuntu 22.04.2 LTS under WSL.

Copied unzipped your paskage folder to my virtual environment: .venv/lib/python3.10/site-packages

When trying to import this I got next:
from pyearth import Earth

AttributeError: module 'numpy' has no attribute 'int'.
np.int was a deprecated alias for the builtin int. To avoid this error in existing code, use int by itself. Doing this will not modify any behavior and is safe. When replacing np.int, you may wish to use e.g. np.int64 or np.int32 to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

numpy version installed 1.21.25...
Sorry for disturbing you a lot, it seems that you are the only one who solved it.. :) thanks for helping me & community as well.

[pgr123]

I use also Ubuntu 22.04 and it works.
I don't use virtual environment.
Surely, your directory .venv/lib/python3.10/site-packages is not the good one. Where is the directory dist-packages ?
Try to copy to /usr/lib/python3/dist-packages.
It is late in France, so we can continue tomorrow if you want.
It's a pleasure for me to contribute.

[twistfire]

Unfortunately I need to work within virtualenvironment for this project.

I suppose that for my case moving to my virtualenvironment directory (/..../path_to_project/.venv/lib/python3.10/site-packages) it's the same as you suggest for global environment... Because VE is isolated.

and we can see that error appears when we import a package which was unzipped. and pylance sees the package... but some issues with data types appear.
will think until tomorrow..
I can't find any alternatives to that library.

[pgr123]

It seems you use numpy 1.21.25 and have you tried with the version I recommanded (numpy 1.21.5) ?
It works with numpy 1.21.5 and scipy 1.10.1.
Do
pip3 install numpy==1.21.5 & pip3 install scipy==1.10.1
and tell me if that work.

[pgr123]

Hello twistfire, did you succeed ?

[twistfire]

Hello @pgr123 thanks for your interest. will test today evening and report here. But found that it's not recommended to use this package with python >3.6 .. but in my project i have to use at least 3.10, maybe can downgrade to 3.9.. So will write.

[pgr123]

Where have you seen that it's not recommended to use this package with python >3.6 ? I don't see why ? What is the reason ?

[pgr123]

Hello twistfire,
I'm glad to know that your problem wasn't so urgent after all !
With version 1.21.5 of numpy everything works !
Have a nice week end.

[twistfire]

@pgr123
Sorry for the late reply. I had an issue with my internet - someone broke my cable, I hadn't internet until today :(

About Python 3.6 and compatibility/dependencies - I googled all the info I could and one of the guys who showed nice results plots commented for a guy who wanted to use it with python 3.9 that he should use 3.6 instead to use compatibility.. (can't find it again).. Nevertheless. I have downgraded the version of numpy to 1.21.5 and broke my current project - I have to use the newest version of numpy there.. because of the pandas dependencies...

But when I created a "clean" Python 3.10.6 virtual environment and installed it all from scratch + -> it worked (!!) - exactly like you suggested. Now I am thinking about how to find a pandas version to work with my hdf5 datasets and use numpy version 1.21.5... :( if it's possible of course.

Here is some result as a test.

So thank you very much for your tries and support!!!

However, it seems that this automated approach is not working like I want for my task... E.g. here is the model data I have - blue dots, and as a fit-result, I got something very poor.... While experiments with the initial demo datasets work well enough. It seems that I need to find and tune some parameters for the fitter - to be more sensitive and catch the signal form I have..

Again, thank you for your efforts and support!

If you want, you can use Orange data mining (https://orangedatamining.com/), there is an addon to do MARS (earth) model and there are many other things interesting.

[twistfire]

@pgr123 Thanks! Did you use the Orange package? I have tried on a local machine and it seems MARS is not provided...

[pgr123]

It seems that this is an addon (https://orangedatamining.com/blog/earth-multivariate-adaptive-regression-splines/) that you must add to orange3. I did not tried it. Say me if you find how it works.

[evertonsantanaj]

I was having the same problems as @twistfire installing in mac and a venv with Python 3.11.

A configuration that worked for me:
pip install ipykernel
pip install openpyxl
pip install matplotlib
pip install pandas
pip install numpy==1.26.2
pip install scipy==1.10.1
pip install Cython==0.29.36

And after that:
python setup.py install --cythonize

I just needed to further adjust some parts in the code that used deprecated versions for int and float in numpy.

py-earth-master_backup_np copy.zip
(please, rename the folder to py-earth before using it)

Thank you for all the comments and discussions here, special kudos to @pgr123 !
