Issue with pip install mambavision==1.1.0

[a32sd33]

I encountered an issue while installing mambavision==1.1.0, specifically with mamba-ssm==2.2.4. The installation fails during the wheel build process with the following error:

NameError: name 'bare_metal_version' is not defined
Additionally, I received a warning stating:

mamba_ssm was requested, but nvcc was not found.
However, I have confirmed that:

NumPy is installed (numpy 2.2.4).

nvcc is available (CUDA 12.6).

PyTorch is installed (torch 2.6.0+cu124).

setuptools, wheel, and pip are up-to-date.

Would you have any insights on how to resolve this issue? Any guidance would be greatly appreciated.

Hi @a32sd33

It may be worth opening up an issue in here and report the problem. But here's my take:

When you see something like 'bare_metal_version', the build script (likely in mamba-ssm’s setup or configuration files) is referencing a variable (bare_metal_version) that hasn’t been defined. This suggests a bug or an oversight in the package’s source code. So makes sense to report the problem to their repo and follow up.

But when you also see "nvcc was not found", then the build script is definitely not detecting nvcc (you may have it installed though). So maybe just make sure the directory containing nvcc (typically /usr/local/cuda/bin) is in your PATH. You can do something like:

export CUDA_HOME=/usr/local/cuda
export PATH=$CUDA_HOME/bin:$PATH

But as far as installing mambavision with pip is concerned, there should be no problems at all if you can install the mamba dependencies.

Hope this helps !
