Cannot run the code, ninja error

[Smoltbob]

I followed your instructions and when running tools/test.py the following error is thrown :

File "/home/travail/jules/anaconda3/envs/HRNet/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 759, in _build_extension_module
    ['ninja', '-v'], stderr=subprocess.STDOUT, cwd=build_directory)
  File "/home/travail/jules/anaconda3/envs/HRNet/lib/python3.6/subprocess.py", line 356, in check_output
    **kwargs).stdout
  File "/home/travail/jules/anaconda3/envs/HRNet/lib/python3.6/subprocess.py", line 438, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

Do you have more details on how to run your code ?
Thanks

Fixed the issue by installing ninja 1.8.2

Fixed the issue by installing ninja 1.8.2

hi, i changed ninja from 1.9.0 to 1.8.2 but the problem still exists, and my env is pytorch==0.4.1, gcc==5.4.0, and beside this problem, i met another problem of ninja as following:

[sunformoon]

@BanaBear Encountered the exactly same error. Would you have a chance to fix it?

[dzyjjpy]

@sunformoon @BanaBear do you solve the issue? I have the same one
#104
My environment:
I tried pytorch 1.0, 1.1, 1.2 on branch-1.1
my environment:
ubuntu:16.04
python:3.6
gcc: 5.4
cuda: 10.0

and I install re2c and ninja by source code.
