problem with the latest version of conda

[elejeune11]

PyEarth doesn't work with Anaconda 2019.03 for macOS (Python 3.7) (the installation fails).

Is this issue being worked out?

Thanks!

@elejeune11 I was not aware. I haven't had much time to work on py-earth lately, and probably won't for a few months at least. Unfortunately, that means as other projects make changes issues like this will start to arise. If you or someone else reading this has time to figure this out and create a pull request, I would be very happy to support you with advice and code reviews.

In the meantime, @elejeune11, would you mind posting here the error message you get when you try to conda install py-earth?

@elejeune11 Did you find a solution? I have Win10 and a clean python 3.7 environment . I also installed also the C++ Build Tools but running python setup.py install or pip install sklearn-contrib-py-earth gives me
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2

A colleague had the same problem, we both solved it simply by using the correct files:

https://pypi.org/project/sklearn-contrib-py-earth/#files

OSX Catalina with Anaconda 2019.10. Compile errors like below, worked around with the advice from another failing build: SheffieldML/GPy#649. find -name '*.pyx' -exec cython {} ;

pyearth/_util.c:8071:21: error: no member named 'exc_type' in 'struct _ts'
*type = tstate->exc_type;
~~~~~~ ^
pyearth/_util.c:8072:22: error: no member named 'exc_value' in 'struct _ts'; did you mean 'curexc_value'?
*value = tstate->exc_value;
^~~~~~~~~
curexc_value

I get exactly the same problem on windows10 python3.8:
running python setup.py install or pip install sklearn-contrib-py-earth

I'm still digging into this myself. If you run the setup with '--cythonize' and import from the new build files it appears to work fine with 3.7

few years later... i have another solution, but more complicated one...
let me elaborate on the error -
at windows, when i install

git clone git://github.com/scikit-learn-contrib/py-earth.git
cd py-earth
python setup.py install

i get errors:

the solution is to enter to pyearch folder from wsl and run

sed -i 's/tstate->exc/tstate->curexc/' *.c

or manually change all
tstate->exc
to
tstate->curexc
at all .c files

then run

python setup.py install

again.
