Error in species-distribution-33-plot

[annaposlednik]

Hi, I'm working on the notebook "species-distribution-33-plot" and can't get the plots to work, as I keep getting this error message:
I have imported hvplot.pandas and there doesn't seem to be a "geoviews" module, so I'm not sure what is wrong.

Thanks in advance for any advice!

@annaposlednik that's weird, it was running for me. Maybe Codespaces is loading a slightly older version of the environment. You can import geoviews with:

import geoviews as gv

Like hvplot.pandas, you don't have to use geoviews directly.

You might find that geoviews isn't installed. In that case, you can run:

!conda install geoviews

which should work. Let me know if you're still running into trouble! I'll be doing the demo video later today, so I'll work through this issue then as well.

@eculler I tried both of these and was still unable to load geoviews. Is there an alternative?

The import did not work, so I have tried to install twice, each time taking ~10m before crashing. Here is the error message:

Collecting package metadata (current_repodata.json): done
Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve.
Solving environment: unsuccessful attempt using repodata from current_repodata.json, retrying with next repodata source.

I also had the same problem, where I tried the installation a few times (each time taking ~10 min) and then receiving the same error message.

I am also in the same spot I tried installing in different ways since it wasn't recognizing 'geoviews' in - import geoviews as gv .

I tried the install and import Dr. Elsa posted and had the same issue, I then tried another install I saw somewhere

conda install -c pyviz geoviews

it then timed out so I tried another import I saw on the Geoviews website

I then tried

pip install geoviews

Which did work quickly and it then recognized the 'import geoviews as gv', but when I run the code cell for creating a simplified GeoDataFrame I get an error message. From what I've read pip commands and conda don't mix well? Not super sure ... I was just trying to see what would work and failed.

@earthlab-education/ea-students @earthlab-education/ea-instructors I think I have a solution for this!

First of all, you will need to reload your Codespace:

1. COMMIT AND SYNC all your work before doing this!
2. Click on the input box in the middle of your Codespace page at the top, and start typing >Rebuild. You should select Codespaces: Rebuild Container
3. Select the Full Rebuild option
4. Prosper! Once the rebuild is complete you should find that you can run the plotting code and/or import geoviews successfully

You can accomplish the same by starting a new codespace, but be sure to delete the old one so you don't run out of disk space and get cut off. I recommend the rebuild! Either way, you will have to download your data again...but on the plus side you wrote code to do it all so it should be a matter of re-running the first two notebooks!

[eculler]

ALSO -- I found that the plotting code took a long time to run on Codespaces (several minutes and counting)! SO...I recommend the following parameters when you run .simplify:

eco_gdf.geometry = eco_gdf.simplify(.1, preserve_topology=False)

I'll go over this all in the video too -- keep an eye out for that tomorrow afternoon.
