fatal error: torch/extension.h

❓ Questions and Help

Hello greate guys,
I followed the installation instructions in INSTALL.md with a little modification by install pythoch through pip.
But when I run the final command to install the pytorch detection, it gave me a fatal error: torch/extension.h: No such file or directory.
Then I found that there has a torch/torch.h file in INCLUDE_PATH (site-packages/torch/lib/include/), which its content is same as the torch/extension.h found in the pytorch source codes.
However, there still has some missing files after I changed torch/extension.h to torch/torch.h, such like ATen/cuda/CUDAContext.h.

Follows are my installation commands:
$ virtualenv -p python3 maskrcnn-benchmark
$ source maskrcnn-benchmark/bin/activate
$ pip install ipython ninja yacs cython matplotlib
$ pip install http://download.pytorch.org/whl/cu80/torch-0.4.1-cp35-cp35m-linux_x86_64.whl
$ pip install torchvision
then follows the install pycocotools and pytorch detection.

Is the installation wrong?

hey guy.I have met the same problem too.Have you found the right way to fix it ?thanks a lot

I think we should install torch_nightly, not the stable one.

[huazai-1994]

ok ,I will have a try .Thanks for your answer

Yes, you should install the preview (nightly) version of PyTorch, which corresponds to PyTorch 1.0

I'm closing the issue, but let me know if you still have issues even after installing the nightly version

Hi, I've already installed pytorch-nightly using:
"conda install --use-local name_of_pytorch-nightly_version_1.0.0.whl"
And I can see pytorch-nightly is successfully installed through "conda list".
However, when I import torch and print version, the result is still "0.4.0"(my orignial version).

How can I cover the old version with newly installed pytorch-nightly? Please help.

I've fixed this issue by installing a stable version of pytorch instead of pytorch-nightly. Thx for the code.
