Error Pre-Training Predictor: "model -> encoder -> encode_source extra fields not permitted (type=value_error.extra)"

[Qbop981001]

When I use the predictor.yaml file in config/ to pretrain the predictor model, I got this error. The original message is:

Traceback (most recent call last):

pydantic.error_wrappers.ValidationError: 1 validation error for Config
model -> encoder -> encode_source
extra fields not permitted (type=value_error.extra)

As the message shows, I assume it is the error of model -> encoder ->encode_source, but in fact I did not revise the original example predictor.yaml file in this project. In the original file, the value of encode_source is set to "false". I tried to override it to "true", and I get the same error.
How can I find the file demonstrating that how the values in .yaml file should be set ?

hey @Qbop981001!

Sorry it took me a while to get a look at this. you are absolutely correct, it is indeed a bug in our example files.

The predictor encoder by default always encodes source, as such, that flag does not make sense and is probably a leftover from another config.

The correct way to fix this is to simply remove the flag from the yaml :)

Let me know if you have any other questions!
