how to evaluate on custom dataset?

[InfiniteSamele]

I have successfully trained models on my custom dataset, however, when it went to the test phase, it showed me the following error, i thought the reason is custom_dataset.py doesn't have generate_prediction_dicts method. And after I read the CUSTOM_DATASET_TOTURIAL.md, it's just too simple about the Evaluation part, I am still confused about how to evalute my model.

Process finished with exit code 1

And the demo.py also gives me an error, can you told me how to fix that?

In my toy case, it can evaluate directly if all config are set well, so we don't write any tutorial for evaluation. In you case, could you check why this is None?
