Python falling back to the ' Python ' engine because the ' C ' engine does is not a support regex separators

O ' Reilly published by Wes McKinney, "Python for Data analysis"

I use the tool: Pycharm 2016.3.2

Warning: parserwarning:falling back to the ' Python ' engine because the ' C ' engine does is not a support regex separators (separators > 1 char and different from ' \s+ ' is interpreted as regex)

Workaround: Add engine= ' python '

Ratings = pd.read_table (' Data\ml-1m\\ratings.dat ', sep= ':: ', Header=none,names=rnames, engine= ' python ')
