Error when running last cell in kitti360_inference.ipynb notebook...

[adikrishnanucd]

@drprojects I was able to import all the necessary modules in the kitti360_inference.ipynb file. However, when I am trying to run the last cell, I get the following error when it calls the hydra_read function:

Do you know how I can fix this error?

Thank you in advance, and sorry for the trouble.

Hi,

I never encountered this issue and can't reproduce it on my end.

This sounds similar to this hydra-python comptibility issue... Have you looked into it ? Can you please share the output of the following commands:

python --version

pip list | grep hydra

pip list | grep omegaconf

Just to be sure: have you made any modification (even minor) to the code ?

Hello @drprojects

These are the results of the three commands:

Python 3.7.9
hydra-core                    1.1.0
omegaconf                     2.3.0

I have made modifications to the variables in the third cell to point to the right paths. Otherwise I haven't made any other edits.

I believe the issue came because my omegaconf was updated to a higher version than what was required by hydra-core==1.1.0. I downgraded omegaconf and it seems to not give me this error anymore. Thank you for the help @drprojects .

Thanks for sharing your solution :wink:

@drprojects I am currently getting this warning that results in the cell being exited.

I have all the files in the corresponding directories. Is there something I need to change to get this code to work? I found that this warning happens when the Trainer is created in the last cell of the kitti360_inference.ipynb notebook.
