I must be doing something wrong but I couldn't manage to compressed a file using a custom trained profile since I was getting this error:

``` src/openzl/codecs/dispatch_string/encode_dispatch_string_binding.c:74: EI_dispatch_string: splitting 48000001 strings into 14 outputs OpenZL Library Exception: OpenZL error code: 55 OpenZL error string: Input does not respect conditions for this node OpenZL error context: Code: Input does not respect conditions for this node Message: Check `eltWidth != 2' failed where: lhs = (unsigned long) 4 rhs = (unsigned long) 2

On the other hand the default CSV profile didn't seem that great either, the CSV file was 349 MB and it compressed it down to 119MB while a ZIP file of the CSV is 105MB.



This is unexpected... I'm interested in seeing what's happening here. Do you mind creating a Github issue with as much info as you're comfortable sharing? https://github.com/facebook/openzl/issues
