Description

I have installed torch 1.13.1 with cuda support on a GPU machine. The following command fails:

firejail --noprofile -- python -c "import torch; print(torch.cuda.is_available())"
Parent pid 3594, child pid 3595
Child process initialized in 2.08 ms
/xxx/.venv/lib/python3.9/site-packages/torch/cuda/__init__.py:88: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:109.)
  return torch._C._cuda_getDeviceCount() > 0
False

Parent is shutting down, bye...

Whereas running it outside of firejail gives:

python -c "import torch; print(torch.cuda.is_available())"
True

Strange thing is that once it has ran outside of firejail once, it will succeed in firejail thereafter. I'm guessing it has to do with lazy initialization of CUDA in Torch. Is there any configuration I can make to make it work in firejail without priorly having to run it outside ?

Steps to Reproduce

All described above

Expected behavior

firejail --noprofile -- python -c "import torch; print(torch.cuda.is_available())" should return True

Actual behavior

It returns False with error message

/xxx/.venv/lib/python3.9/site-packages/torch/cuda/__init__.py:88: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:109.)
  return torch._C._cuda_getDeviceCount() > 0

Behavior without a profile

as described in the description.

Additional context

Environment

  • firejail version 0.9.62
  • Python 3.9.5
  • torch==1.13.1
  • CUDA 11.7
  • Ubuntu 20.04

Checklist

  • The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
  • I can reproduce the issue without custom modifications (e.g. globals.local).
  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • The profile (and redirect profile if exists) hasn't already been fixed upstream.
  • I have performed a short search for similar issues (to avoid opening a duplicate).
    • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
  • I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

Original GitHub issue: https://github.com/netblue30/firejail/issues/5623 <!-- See the following links for help with formatting: https://guides.github.com/features/mastering-markdown/ https://docs.github.com/en/github/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax --> ### Description I have installed torch 1.13.1 with cuda support on a GPU machine. The following command fails: ``` firejail --noprofile -- python -c "import torch; print(torch.cuda.is_available())" Parent pid 3594, child pid 3595 Child process initialized in 2.08 ms /xxx/.venv/lib/python3.9/site-packages/torch/cuda/__init__.py:88: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:109.) return torch._C._cuda_getDeviceCount() > 0 False Parent is shutting down, bye... ``` Whereas running it outside of firejail gives: ``` python -c "import torch; print(torch.cuda.is_available())" True ``` Strange thing is that once it has ran outside of firejail once, it will succeed in firejail thereafter. I'm guessing it has to do with lazy initialization of CUDA in Torch. Is there any configuration I can make to make it work in firejail without priorly having to run it outside ? ### Steps to Reproduce All described above ### Expected behavior `firejail --noprofile -- python -c "import torch; print(torch.cuda.is_available())"` should return `True` ### Actual behavior It returns `False` with error message ``` /xxx/.venv/lib/python3.9/site-packages/torch/cuda/__init__.py:88: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:109.) return torch._C._cuda_getDeviceCount() > 0 ``` ### Behavior without a profile as described in the description. ### Additional context ### Environment * firejail version 0.9.62 * Python 3.9.5 * torch==1.13.1 * CUDA 11.7 * Ubuntu 20.04 ### Checklist <!-- Note: Items are checked with an "x", like so: - [x] This is a checked item. --> - [x] The issues is caused by firejail (i.e. running the program by path (e.g. `/usr/bin/vlc`) "fixes" it). - [x] I can reproduce the issue without custom modifications (e.g. globals.local). - [ ] The program has a profile. (If not, request one in `https://github.com/netblue30/firejail/issues/1139`) - [ ] The profile (and redirect profile if exists) hasn't already been fixed [upstream](https://github.com/netblue30/firejail/tree/master/etc). - [x] I have performed a short search for similar issues (to avoid opening a duplicate). - [ ] I'm aware of `browser-allow-drm yes`/`browser-disable-u2f no` in `firejail.config` to allow DRM/U2F in browsers. - [ ] I used `--profile=PROFILENAME` to set the right profile.

@achsvg on Jan 27:

I have installed torch 1.13.1 with cuda support on a GPU machine. The
following command fails:

firejail --noprofile -- python -c "import torch; print(torch.cuda.is_available())"
Parent pid 3594, child pid 3595
Child process initialized in 2.08 ms
/xxx/.venv/lib/python3.9/site-packages/torch/cuda/__init__.py:88: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:109.)
  return torch._C._cuda_getDeviceCount() > 0
False

Parent is shutting down, bye...

Whereas running it outside of firejail gives:

python -c "import torch; print(torch.cuda.is_available())"
True

Interesting; does it work with firejail --profile=noprofile?

noprofile.profile removes even more restrictions than using --noprofile.

  • firejail version 0.9.62
  • Python 3.9.5
  • torch==1.13.1
  • CUDA 11.7
  • Ubuntu 20.04

Note that we do not maintain that firejail version:

What happens with the latest released firejail version?

@achsvg commented on GitHub (Jan 27, 2023):

Some options in noprofile are not supported by the version I'm using but after removing them it works! So I managed to bisect which option affects the CUDA loading. And it looks like when allow-debuggers is in the profile it works. Not sure why CUDA would need this though...

I'm not able to test the latest released version yet but will try later.
