[nguyenquocthaoolli]

Step:
python

output = replicate.run(
        "paper11667/clipstyler:f2d6b24e6002f25f77ae89c2b0a5987daa6d0bf751b858b94b8416e8542434d1",
        input={
        "image":"https://replicate.delivery/mgxm/e4500aa0-f71b-42ff-a540-aadb44c8d1b2/face.jpg",
        "text":"sketch with crayon",
        "iterations":10
    }
        )

Expected: run normally
Error: raise Exception "Invalid version: 'dev'"

Thanks for reporting this, @nguyenquocthaoolli. The exception is being raised because that specific version of paper11667/clipstyler was built with an invalid version of Cog:

'cog_version': 'dev'

The exception is being raised when we try to parse that version as a valid SemVer here:

replicate-python/replicate/schema.py

Line 8 in afe0092

return version.parse(cog_version) < version.parse("0.3.9")

This should be an easy fix, and I'll get working on this now.

@nguyenquocthaoolli This should be fixed in 0.15.2. Please upgrade your installation of the replicate package and let me know if you're still having this issue. Thanks!
