I am trying to use Python to call a Google Cloud AI platform training API. The path to my service account key JSON file is "/Users/my_mac_username/service_account_key.json", and I added the export statement in the bash_profile file so that it looks like:

# Setting PATH for Python 3.8
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
export PATH
export GOOGLE_APPLICATION_CREDENTIALS="/Users/my_mac_username/service_account_key.json"

However, I still got the error:

google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials.

Besides, I have google-cloud-sdk folder installed. I would like to know in which file I should set the environment variable. Thanks for your help!

Assuming your terminal shell is bash, you have your environment variable setup correctly. The new variable will not be available until you reopen the terminal or run source ~/.bash_profile in the current terminal.

If you are running zsh, add the export in your ~/.zshrc file.

To determine which shell you're currently running, use: echo $SHELL from the command line
