I don't understand how is this going to change the initial variable definition, how should it be provided, I already provided anyscale api key and still cannot use the command :

canonopy new test

This is the error that I get :

(canopy-env) kingsize@Goncalos-MacBook-Pro-3 EdGenAI % canopy new test
Canopy is going to create a new index named canopy--test with the following initialization parameters:
{}

Do you want to continue? [y/N]: y
Error: Failed to create a new index. Reason:
Canopy has failed to infer vectors' dimensionality using the selected encoder: OpenAIRecordEncoder. You can provide the dimension manually, try using a different encoder, or fix the underlying error:
Failed to enconde documents using OpenAIRecordEncoder. Error: Your OpenAI account seem to have reached the rate limit.
