Error running tao_deploy container on google colab

Good morning,
I tried to run the tao-deploy notebook in order to create a TensorRT engine for PeopleNet model. When I try to run the section 7) I got the following error:

/usr/local/lib/python3.8/dist-packages/pycuda/compyte/ FutureWarning: In the future np.bool will be defined as the corresponding NumPy scalar.
reg.get_or_register_dtype(“bool”, np.bool)

AttributeError: module ‘numpy’ has no attribute ‘bool’.
np.bool was a deprecated alias for the builtin bool. To avoid this error in existing code, use bool by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.bool_ here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:

Any suggestions?


Could you please share the full log? It is better to save as html file and upload. Thanks.

attached is the notebook converted in HTML. Compared to the orignal one’s the only thing I changed is the TensorRT version to since I downloaded the tar from TensorRT 8.5 GA Update 2

tao_deploy.html (709.4 KB)

Could you refer to python - How to solve AttributeError: module 'numpy' has no attribute 'bool'? - Stack Overflow to use another version of numpy?

I fixed the problem running the following code before conversion

!python3.8 -m pip install numpy==1.23.4
