Install Failed about mamba HOT 6 OPEN

I don't have enough information. What OS are you using?

from mamba.

post the full stack trace. But kinda looks like you're missing nvcc

from mamba.

I had the same issue, bare_metal_version is only defined in the setup.py if the CUDA_HOME environment variable is set, but the 11.8 version check is outside of that if block:

CUDA 11.8 was installed on my machine, so once I set the CUDA_HOME variable I could install the package.
Maybe an error message about CUDA_HOME would be helpful?

how do you set the home variable? I'm having this same issue. Thanks in advance

from mamba.

It depends on the location and version of your cuda installation, for me it was this:
export CUDA_HOME=/usr/local/cuda-11.8

from mamba.

Has this been solved? Thanks!
