When the same data is read from the csv file, this results in an error:

df['geo_fence'] = df['geo_fence'].apply(wkt.loads)

WKTReadingError: Could not create geometry because of errors while reading input.

The error appears when the row data is in form of MULTIPOLYGON(P1,P2,P3) etc but not for MULTIPOLYGON(P1)
