ImportError: cannot import name 'h3' from 'h3' while importing h3pandas in Colab for polyfill

I have Colab project that uses h3pandas for polyfill, but importing h3pandas throws an ImportError.

After adding these libraries:

!pip install h3pandas
import pandas as pd
import matplotlib.pyplot as plt
import h3pandas

I get this error:

ImportError                               Traceback (most recent call last)
<ipython-input-2-5e53e9308d98> in <cell line: 3>()
      1 import pandas as pd
      2 import matplotlib.pyplot as plt
----> 3 import h3pandas

     12 from pandas.core.frame import DataFrame
     13 from geopandas.geodataframe import GeoDataFrame`

ImportError: cannot import name 'h3' from 'h3' (/usr/local/lib/python3.10/dist-packages/h3/__init__.py)

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

This is a known bug in H3-Pandas. As of h3-py v4.0.0, the name h3.h3 no longer exists, so the line from h3 import h3 in the H3-Pandas source code throws an ImportError.

As a workaround, you can manually install a version of H3 that still includes that name. Any v3 release will work - at the time of this writing, the most recent is v3.7.7, but you can also just pip install h3~=3.0.

!pip install h3pandas
!pip install h3~=3.0
import pandas as pd
import matplotlib.pyplot as plt
import h3pandas
