Anyone using geopandas? #23

Closed NadineSahin closed 6 years ago

NadineSahin commented 6 years ago

Is anyone using Geopandas and want to share information on how to install it properly and import it?

I am trying to install geopandas with: pip install geopandas it installs correctly, but when importing it using import geopandas as gpd

I get this error:

ImportError Traceback (most recent call last)

Geopandas should not be installed with pip for technical reasons.

@NadineSahin did you manage to solve this? Otherwise I'm in my office tomorrow morning.

I get the same error. I used: conda install -c conda-forge geopandas

abjer commented 6 years ago

@Viola0 did you solve this? It sounds like you have a previous version that you installed via pip which causes the malfunction.

When using geopandas and sucesfully created a geodataframe and now want to plot areas of the map by concentration of say population. How should we do it? Any good ideas?

Viola0 commented 6 years ago

@abjer I still havn't solved it. I didn't use pip the first time (but I tried it afterwards) so I don't think that's the problem. I've talked to another group, where they were only able to import geopandas on one computer after the installation, so it seems like it's a pretty normal problem..

@abjer according to this discussion https://github.com/geopandas/geopandas/issues/237 it should help to install it in a new environment, but I can't figure out how that works

@Viola0

You need to open your command prompt / terminal where you have access to conda. Then you need to

  1. create the environment
  2. activate the environment
  3. install relevant packages, e.g.
    • conda install -c conda-forge geopandas jupyter scipy scikit-learn seaborn -y
  4. while the environment is still active, add the jupyter kernel using
    • python -m ipykernel install --user
  5. start jupyter notebook again - now under new it should have the possibility of making a notebook using your new environment
