[sherleens]

I got this error for the install, could you provide any solution?

@sherleens
According to the error information "nvcc: command not found", I suggest you check whether the CUDA is correctly installed.

[AceCoooool]

I also meet a make error.
The error like:

Is this due to the #include <THC/THCGenerateFloatType.h> ?
And I also just run build.py to create this extension C, the problem is also exist.

[sherleens]

@yeezhu Thanks, the problem is solved:).

[yeezhu]

@AceCoooool
Please try to update your PyTorch to the latest version.

[AceCoooool]

I use the pytorch 0.2.0 (through conda)? (your version is installed through source? --- I will try it)

OK, I can run it in my own computer, (install through source --- but I am not sure whether it can run on a conda install version. )

Thank you @yeezhu 😀

I am sorry to ask again: (I have a question about the build process)：
Why run python build.py with the error fatal error: generic/SoftProposalGenerator.c: No such file or directory (I think it may caused by do not include this files)
But bash make.sh is right. ~ !
As far as I know: just run python build.py can create the .so file in _ext.libspn files. Is there any "magic" in setup? 😂

[yeezhu]

@AceCoooool
Haha, no magic...
We setup spn in two steps, firstly build C++/Cuda code to python extension, and then packaging the SoftProposal as python class.

[ZhouYanzhao]

@AceCoooool
You need to compile CUDA kernel functions with nvcc first (check here). That's the "magical" part :)

[AceCoooool]

No, I have already compile CUDA kernel before. It's my fault: If I only run python build.py, it cannot find the generic/SoftProposalGenerator.c (python setup.py can find it due to this line: packages=find_packages(exclude=["build"])), so just add this file in python build.py can solve it. (I am so boring to ask this silly question 😂 , just do not want to add a package in python's site-package)

Thank you @yeezhu @ZhouYanzhao . You are so warmhearted ❤️

@sherleens , you can close this issue.

[emigmo]

I have install Pytorch (through pip install, not from source or conda)
But "bash make.sh" there are:
Compiling cuda kernels... rm: cannot remove 'libspn_kernel.cu.o': No such file or directory Installing extension... Package libffi was not found in the pkg-config search path. Perhaps you should add the directory containing libffi.pc'

`
Should I uninstall Pytorch and install from conda or from source?

[yeezhu]

@emigmo
I provided a file named environment.yml which can help you check the environment :)
