[JINO-ROHIT]

This tries to add some verbose message when users pass layers_to_transform and layers_pattern addressing point 3 in #2155.

@JINO-ROHIT Please let me know if the PR is ready for review (always ping me if it's ready).

[JINO-ROHIT]

Hi @BenjaminBossan yeap this is ready for review, im not sure why the other PR commits are being displayed here

[BenjaminBossan]

Wait, how is this PR different from #2159?

[JINO-ROHIT]

yeah actually #2159 simply adds the check if

if self.layers_to_transform is not None and self.layers_pattern is None:
            raise ValueError(
                "When `layers_to_transform` is specified, `layers_pattern` must also be specified. "
            )

This PR is making the error message better logging for layers_transform and layers_pattern if specified, this commit basically - 1f26074

Looks weird that the other commits are being shown here

Yes, I can't really review this PR because of that. Probably it's easiest to just open a new PR and ensuring it only contains the commit intended for that PR.

[JINO-ROHIT]

sure
