training - Githubissues

ucb-pb commented 3 years ago

Thank you for sharing your work! I'm trying to figure out how to start training, but am not very familiar with hydra and am running into errors with it. I modified conf/dataset.yaml, but also changed it back to what it was originally and it still gives the same error. Perhaps you might have an idea what the problem is?

As a side note, a requirements.txt file would be useful to include in this repo

gyupro commented 2 years ago

I solved this problem. Remove hydra and hydra-core and reinstall hydra-core by typing pip install hydra-core==1.1.0.dev3

There is an environment.yaml file in the repository to be used with conda as alternative for a requirements.txt
