setup RCNN failure

Hi All,

Having issues runing the python setup.py build develop step in the setup.

I have cuda 10.2 install on windows 10 running python 3.6 in cuda with the proper torch version. Have visual c build tools 2019 install which looks to be compatible with cude 10.2 and pytorch. However I receive the following errors on the command.

Traceback (most recent call last):
  File "C:\Users\datascience\anaconda3\envs\GracoNet-Object-Placement\lib\site-packages\torch\utils\cpp_extension.py", line 1672, in _run_ninja_build
    env=env)

    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

I would really appreciate some direction! Thanks!

Seems like it was a windows issue. Worked fine on Ubuntu 18.04
