Google Colab Implementation

[sarahshi]

Hi,

Hope this message finds you well. I developed a teaching module using PyGMT back in February using Google Colab. I used this described solution to import PyGMT and things worked well. It sometimes took running the import cell another time -- some folks got an error upon first run -- but things worked successfully

I am currently preparing to teach this module again and just tried running through the code again. I am now getting the error appended. Do you know what may be causing this error? I didn't find any solutions on the forum and figured I may raise the issue here. Thanks in advance for any guidance.

Best,
Sarah

I just tried the PyGMT demo (https://colab.research.google.com/github/GenericMappingTools/try-gmt/blob/master/python-demo.ipynb) and it works well for me. So it means the solution still works.

Maybe you have to run the install commands in a separate cell?

!pip install -q condacolab
import condacolab
condacolab.install()

!pip install -q condacolab
import condacolab
condacolab.install()

Running the above commands in a separate cell works well for me.

That error looks similar to #37 (comment), and I think is due to out of sync dependencies on conda-forge. Maybe the recent PRs like conda-forge/gmt-feedstock#260 fixed it already?

Closing the issue as Google Colab works well for me.
