Hi,i'm working on Windows 10,python 3.6.7 and get error as below when runing .scripts\demo_inference.py with nessary parameters.

I did check that there was no file named deform_conv_cuda in that directory but file like deform_conv_cuda.cpp in dcn/src

same problem

[Fang-Haoshu]

Hi, I guess it's a problem from here: https://github.com/MVIG-SJTU/AlphaPose/blob/master/setup.py#L124 You can try to remove the if command. We will update the setup.py later

I have the same error. Were you able to resolve it, @shartoo

not yet,remove code as @Fang-Haoshu Fang-Haoshu could not help.

[timiderinola]

I had the problem and I've been able to solve it by doing what @Fang-Haoshu said. There is an if statement that makes setup.py skip some module installations if you're on Windows.

• Go to setup.py in your Alphapose folder.
• On line 124, comment out the "if" statement.

if platform.system() != 'Windows': ..........ext_modules = [...

• Ensure you adjust the code block under the if statement (since you have removed the "if"). Make them one indent instead of two.

After doing this, run setup.py again:

$ python setup.py build develop

This time, 'deform_conv_cuda' and other modules will be installed and you should stop seeing this error. It worked for me.

Thank you @timiderinola

[myounus96]

But now I am getting cuda related error, dont know why even I installed cpu version of pytorch.

[Jeff-sjtu]

Hi @M-Younus, GPU version of PyTorch is necessary.

[myounus96]

Hi @M-Younus, GPU version of PyTorch is necessary.

Right,Thanks for response. Please, can you look into this https://github.com/MVIG-SJTU/AlphaPose/issues/503

[myounus96]

Hi @M-Younus, GPU version of PyTorch is necessary.

BTW just for confirmation, the master branch is pytorch based,am I right?As mentioned here https://github.com/MVIG-SJTU/AlphaPose/tree/pytorch#notice

[Jeff-sjtu]

Yes, the master branch is based on PyTorch.

[GreenTeaHua]

setup.py line 124：if platform.system() != 'Windows': ---》if platform.system() == 'Windows': for me，win10+pytorch1.3.1+vs2019+cuda10.1,it's ok.

[aFewThings]

I followed @timiderinola and I got this error. error: command 'C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v10.0\\bin\\nvcc.exe' failed with exit status 2 My version is window10+pytorch1.2.0+cuda10.0

[Fang-Haoshu]

@aFewThings Is VS 2019 installed? If not, I recommend using the pytorch branch, which does not require VS.

[aFewThings]

thx.

[Fang-Haoshu]

Solved. Close

Thx for solving the problem that had been bothering me for several days!
