I'm quite a python newbie so maybe this could be obvious to most people, but reading a json file (with lot of blanks instead of valid GPS coordinates) and trying to copy from this tutorial leads to a big bold error: RecursionError: maximum recursion depth exceeded in comparison.
I think this is because variables are passed as objects instead of float64 or other base types.
Adding this code after pd.read_json() converts blanks to valid GPS coordinates and downscales variable types to float64 and folium works as expected.
df['longitudine'] = df['longitudine'].replace(r'\s+', np.nan, regex=True)
df['longitudine'] = df['longitudine'].replace(r'^$', np.nan, regex=True)
df['longitudine'] = df['longitudine'].fillna(-0.99999)
df['longitudine'] = pd.to_numeric(df['longitudine'])
df['latitudine'] = df['latitudine'].replace(r'\s+', np.nan, regex=True)
df['latitudine'] = df['latitudine'].replace(r'^$', np.nan, regex=True)
df['latitudine'] = df['latitudine'].fillna(-0.99999)
df['latitudine'] = pd.to_numeric(df['latitudine'])
Sample output can be found here.
Expected Output
No error, or at least a warning such as "Folium can't directly work on object types: pass base types such as float64 or expect problems".
Output of folium.__version__
0.8.3
