An issue after intall new version of marvin for MPL-10

[mj-astrotoy]

Describe the bug I installed new version marvin for MPL-10. I could not import marvin in python. This issue seems to be same as one of the below post. I would like to add the error message and result of "check_marvin" on terminal to help you.

This is the check list when "check_marvin" on terminal.

@mj-astrotoy ok thanks, I'll take a look. What version of marvin did you have before? And you just ran pip install -U sdss-marvin, correct?

[havok2063]

@mj-astrotoy Can you do the following in an python session and tell me what it says?

import tree
tree.__file__

It looks like you might be using a standalone package of sdss-tree. If that's the case can you try running pip install -U sdss-tree and pip install -U sdss-access and trying again?
