Any chance you can share the offending file?

Unfortunately the answer is probably no if the file is sufficiently old.

Hi,
I have need for reading some pickle files containing yt array outputs. The files were created by someone else a while ago so I don’t know much about the conditions of their creation. When trying to open them I get the error below.

I am asking here because the comment on line 1384 of the traceback seems to point at a yt issue, not something in the file itself. Has anyone encountered this? Is there a workaround?

Thanks

JT
