See original GitHub issueHello! I’ve been trying metaflow but I got stuck on tutorial number 04.
This is what i get when trying to execute it:

We made a recent release with a comment to that effect. You are right that the environment you use to execute Episode 4 is isolated. The issue is that Episode 4 reads an artifact produced in Episode 2 which used your system Pandas version (it must have been 1.0+). Pandas has breaking changes between 0.24.2 and 1.0+ so 0.24.2 (the version used in Episode 4) can’t read the artifact produced by 1.0+ (the version used in Episode 2). In a future release, we will update the version of the Pandas version used in Episode 4 to be more recent and alleviate these issues. Apologies for not noting this in this issue at the time of release.
Sure. I’ve just did it. The problem persists though.
