Geopandas: compatibility with Pysal 2.0.0

[StevenLi-DS]

Geopandas: 0.4.0
My firends was trying to plot some maps with .plot() method of GeoDataFrame but got the following error wiht pysal 2.0.0 installed.



After

conda install pysal=1.14.4

Everything works. I check the new doc for pysal 2.0.0 and it seems like the structure of the package changed, so I wonder when will geopandas support pysal 2.0.0 so that I can upgrade it?

This is already fixed on master (by using only mapclassify instead of relying on the full of pysal). I hope to release shortly (in a week or so).

@StevenLi-DS Thanks for filing the report! Next time, copying/pasting the stack trace, rather than providing screenshots, would be preferable. That allows keyword searching as well as potentially copying/pasting on the part of someone trying to reproduce the error, not to mention generally being easier to read.

[StevenLi-DS]

@jdmcbr it didn't happen on my end. sorry about that.

@jorisvandenbossche any word on this fix release?

Also, to add a searchable code snippet + stack trace (as I couldn't find this issue when I was searching):

Geopandas (v0.4) doesn't recognize that PySAL (v2.0.0) is installed when running gdf.plot() and passing the scheme keyword argument. I'm doing this in a conda env on Win 10 with Python 3.7.

import geopandas as gpd
import matplotlib.pyplot as plt
import pysal
gdf_world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
gdf_world.plot(column='pop_est', scheme='Quantiles')

ModuleNotFoundError                       Traceback (most recent call last)

    535             Quantiles, Equal_Interval, Fisher_Jenks)

ModuleNotFoundError: No module named 'pysal.esda'

During handling of the above exception, another exception occurred:

ImportError: PySAL is required to use the 'scheme' keyword

I'm currently working around this with the following hack:

1. Install PySAL 2.0 and Geopandas 0.4 (maybe via conda)
2. pip install -U --no-deps mapclassify git+git://github.com/geopandas/geopandas.git@master

That seems to do the trick.

OK, I will do a small 0.4.1 bug fix release today, to get this out.
I am still intending to do the 0.5.0 release shortly, but since that has been my intention for already some time .. probably better to make sure at least the fiona and pysal compatibility fixes are out.

Hi @StevenLi-DS I also downgraded my Pysal into 1.14.4, but the new error raised:

.....
.....
  File "F:\Python\lib\site-packages\matplotlib\artist.py", line 881, in _update_property
    raise AttributeError('Unknown property %s' % k)

AttributeError: Unknown property scheme

I had installed geopandas-0.4.0 , matplotlib-2.2.2, GDAL-2.3.3 , and geopandas-0.4.0+56.gca3216e mapclassify-2.0.1 following the method by @darribas .

I also posted a similar and detailed question at StackOverflow.

Thanks for checking !!

Update: 0.4.1 release was pushed to pypi yesterday, and is also already available on conda-forge
