some problems about "python setup.py build develop"

I type "python setup.py build develop" and there are some errors I can not solve them.

There is error information:

   ......

Can anyone help me? Thanks~

Maybe you should try it in linux sys. I believe the code is build for linux,not for windows.

man,I have same problem in ubuntu

Have you solved your problem? I have the same problem!

i have the same question

I have the similar problem. running build running build_ext /home/hxy/.local/lib/python3.6/site-packages/torch/utils/cpp_extension.py:335: UserWarning: Attempted to use ninja as the BuildExtension backend but we could not find ninja..

Same here. I am not far into the problem, but it seems to have problems to compile the extensions.

EDIT: So now I figured out my problem (seems like finishing the building process complete, with just a few deprecation warnings), but your problem might differ. I try to respond as most as I can.

@keyboardmilk: At least you printed the complete error message. Your problem seems to be your cuda version. Your Error message says: nvcc fatal : Value 'c++14' is not defined for option 'std'. This might be the problem of this issue but I am not completly shure: https://github.com/pytorch/pytorch/issues/32135

@Minghy: It seems you dont have my problem, but you also cut your Error message after the compilations try. If you have the same error message as @keyboardmilk you might have a similar problem.

My actual problem: I was missing Python.h file. It was installed for older versions of Python, but for the one I used. So my fix was simply this: sudo apt-get install Python3.8-dev

I also have the same question,have you solved? `The above exception was the direct cause of the following exception:

@zhyunxiang As I mentioned in my solution the problem was not inside the python setup script. It was a problem in compile time of the C++ libraries.

As your message prints out : The above exception was the direct cause of the following exception: you have a similar problem inside the C++ compile time. Look up your output above this line. Somewher you might find the information you need. If the Output says: missing Python.h you probably need to install the devkit for your Python Env. Since I am using Python3.8 I needed to install python3.8-dev. Before you start installing it you might want to locate it first:

> locate Python.h
/usr/include/python3.8/Python.h

The output above is what I see on my System. If you locate it not in your venv or /usr/include/ maybe something went wrong with your pathing.

If you got a similar message as @keyboardmilk you might endup installing the wrong cuda setup.

@MaKaNu Thanks a lot! You're right, I've solved the problem.
