Hello,  
Am using the CV model for the first time and received the following error  
TypeError: expected str, bytes or os.PathLike object, not float

But from the log file I can’t figure out what this is referring to. From a similar post it seems it may be an issue with one of my input files lacking spatial reference, but I can’t interpret which one (and I’ve checked all the files in ArcGIS and they do have). Please help! Log file attached.

Thanks,

Hi @mhayden , thanks for posting. I think the problem might be with one of the filepaths embedded in the habitat table csv. The `path` column of that table needs to be an absolute path or a relative path (relative to the csv). The error is indicating maybe there is a number or a blank value instead? If you can’t figure it out, please share the habitat table csv here.

Thanks,

Thanks @dave! I had a relative filepath issue.
