assert masks TypeError

[sakird]

On line 101 of custom.py there is an assert line:

assert handler is not None

and below it, there is a TypeError raised if assert is true:

if handler is None: raise TypeError("Your input type to custom model is not currently supported")

this TypeError is not returning to developer and makes it hard to understand the cause of the error.

It seems asserting line is not necessary. Can we remove it?

Here is an image of relevant code and its link:

snowflake-ml-python/snowflake/ml/model/_packager/model_handlers/custom.py

Line 101 in 7bc5f40

assert handler is not None

Hey @sakird , thanks for reporting this issue and we removed this assertion in the next release.

Apart from the the assertion, is it possible for you to provide a minimal reproducible example so that we can help investigate the issue?

Thanks,
Xinyi

Would it be OK to provide code here as a comment? Or is there any other way for that? I did not do anything like this before.

Hey @sakird, you can delete your sensitive information, create dummy data and share codes in the comment.
Otherwise, if you have any point of contact sales engineer, you can also share with them and i'm happy to help.

Thanks
