[BUG] Import Error involving Metadata

[virati]

Import of pysindy in a Google Colab Notebook (pro) does not work - yields a "ContextualVersionConflict" error.

Reproducing code example:

!pip install pysindy
import pysindy as sindy

Error message:

---

ContextualVersionConflict Traceback (most recent call last)
