[yt-users] issue with reading pickle files with yt-conda

[Jason Tumlinson]

Hi Nathan,

Here is a link to the possibly stale pickle:

Hope we can find a solution.
Thanks
JT

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
