!!

          ********************************************************************************
          An error happened while installing `SAM 2` in editable mode.

          The following steps are recommended to help debug this problem:

          - Try to install the project normally, without using the editable mode.
            Does the error still persist?
            (If it does, try fixing the problem before attempting the editable mode).
          - If you are using binary extensions, make sure you have all OS-level
            dependencies installed (e.g. compilers, toolchains, binary libraries, ...).
          - Try the latest version of setuptools (maybe the error was already fixed).
          - If you (or your project dependencies) are using any setuptools extension
            or customization, make sure they support the editable mode.

          After following the steps above, if the problem still persists and
          you think this is related to how setuptools handles editable installations,
          please submit a reproducible example
          (see https://stackoverflow.com/help/minimal-reproducible-example) to:

              https://github.com/pypa/setuptools/issues

          See https://setuptools.pypa.io/en/latest/userguide/development_mode.html for details.

[dehaozhou]

I also encountered the same problem.

[kaia-li]

I also met the same error.

[SJLNNU]

I also encountered the same problem.
Installed pytorch using conda,without installing CUDA.
How to fix this ?

[someshfengde]

Getting the same error on M2 Air. Can't we use this without cuda?

[fritol]

stinks

[fritol]

worked for me:

install torch nightly!
install CUDA 12.1
run the sam2 pip command

[Zhui-Meng666]

The Win11 platform also encountered the same problem. The CUDA_COME environment variable was also set, but it was useless. How should I install it?

[Eranio-bit]

Have the same issue

OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.

I have CUDA 12.1 with nightly installed in the main python env

[Guo1ZY]

I have similar issue relating to this, since I run the command "pip install -e . " on ubuntu20.04, the other environment dependences seems downloading well, however the terminal report an error with cuda ==>" running build_ext
error: [Errno 2] No such file or directory: '/usr/local/cuda:/usr/local/cuda:/usr/local/cuda11.8/bin/nvcc'
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
I set the environment on annaconda with python3.11 and cuda11.8,The CUDA_COME environment variable was set as well,
How should I solve this problem?

[SJLNNU]

I also encountered the same problem. Installed pytorch using conda,without installing CUDA. How to fix this ?

update my solution:
1 Installed CUDA=12.6 CUDNN
2 Set CUDA_HOME environment variable
3 run "pip install --no-build-isolation -e ."
4 #48

[jjun-2020]

I also encountered the same problem. Installed pytorch using conda,without installing CUDA. How to fix this ?

my torch version 2.3.1+cu121, Is it impossible to use (something) if CUDA is not installed?

          ********************************************************************************
          An error happened while installing `SAM 2` in editable mode.

          The following steps are recommended to help debug this problem:

          - Try to install the project normally, without using the editable mode.
            Does the error still persist?
            (If it does, try fixing the problem before attempting the editable mode).
          - If you are using binary extensions, make sure you have all OS-level
            dependencies installed (e.g. compilers, toolchains, binary libraries, ...).
          - Try the latest version of setuptools (maybe the error was already fixed).
          - If you (or your project dependencies) are using any setuptools extension
            or customization, make sure they support the editable mode.

          After following the steps above, if the problem still persists and
          you think this is related to how setuptools handles editable installations,
          please submit a reproducible example
          (see https://stackoverflow.com/help/minimal-reproducible-example) to:

              https://github.com/pypa/setuptools/issues

          See https://setuptools.pypa.io/en/latest/userguide/development_mode.html for details.

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building editable for SAM-2 Failed to build SAM-2 ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (SAM-2)

Have you tried pip install --upgrade ninja wheel? Then run pip install --no-build-isolation -e . again

[RCLaplace]

pip install --upgrade ninja wheel

I tired it but still got the same error

Hi @RCLaplace @SJLNNU @kaia-li @Zhui-Meng666 @Zhui-Meng666 @jjun-2020 @Guo1ZY @Eranio-bit @someshfengde , we have recently made the CUDA extension step optional (in https://github.com/facebookresearch/segment-anything-2/pull/155) as a workaround to this problem.

You can pull the latest code and reinstall via

# run the line below inside the SAM 2 repo
git pull;
pip uninstall -y SAM-2;
rm -f sam2/*.so;
pip install -e ".[demo]"

which allows using SAM 2 without CUDA extension (the results should stay the same in most cases, see INSTALL.md for details).

thank you :)
