While I was importing the library

from mapsplotlib import mapsplot as mplt

It prompts me the error

File "C:\ProgramData\Anaconda3\lib\site-packages\mapsplotlib\mapsplot.py", line 213
print '[WARN] Cannot draw polygon for cluster {} - only {} samples.'.format(c, in_polygon.sum())

SyntaxError: invalid syntax

Please advise what to do
