run groundingdino in sagemaker gpu instances

[llealgt]

I'm tryng to run groundingDino in a notebook in AWS sagemaker studio, I run the installation and I got the error:

NameError: name '_C' is not defined

I know the instructions are explicit about needing the CUDA_HOME variable to solve it, so I checked and indeed the variable is not set, but the issue is that I don't know where cuda is installed in sagemaker instances, if I check the common cuda path
/usr/local/
I cannot find any cuda folder. Has anyone used groundingdino with sagemaker gpu instances? where is cuda installed so I can add it to the CUDA_HOME variable and solve NameError: name '_C' is not defined
