Import problem in Google Colab

[konstantinklemmer]

Currently, there is an issue with importing pysal into a Google Colab notebook.

Since pysal is not one of the standard packages for Colab, it needs to be installed using !pip install pysal in the notebook. The installation works fine, but once import pysal is called, the following error comes up

ContextualVersionConflict: (python-dateutil 2.8.1 (/usr/local/lib/python3.6/dist-packages), Requirement.parse('python-dateutil<=2.8.0'), {'quilt3'})

So apparently, the python-dateutil package needs to be downgraded to version 2.8.0, which can be done calling !pip install -U python-dateutil==2.8.0 at the very beginning of the notebook, however this is still an annoying issue that I wanted to make you aware of!

@knaaptime this looks like an issue with tobler/quilt dependency?

[knaaptime]

Yeah we can remove that dep. on my to do list for this week

Thanks for the quick replies, awesome guys!

[knaaptime]

tobler 0.3.0 removes the dateutil dependency and is live on pip

[knaaptime]

unfortunately, we still have that hardcoded in this pysal release, but we'll make sure it's removed for the next

@knaaptime i missed this in the 2.3.0 release. I'm assuming we can remove the pinning now?

[knaaptime]

yeah we can remove it
