How can I tell the warnings to go away?
If it's this type of floating point related stuff, you can use np.seterr In [1]: import numpy as np In [2]: np.log(1./np.array(0)) Warning: divide by zero encountered in divide Out[2]: inf In [3]: orig_settings = np.seterr() In [4]: np.seterr(all="ignore") Out[4]: {'divide': 'print', 'invalid': 'print', 'over': 'print', 'under': 'ignor e'} In [5]: np.log(1./np.array(0)) Out[5]: inf In [6]: np.seterr(**orig_settings) Out[6]: {'divide': 'ignore', 'invalid': 'ignore', 'over': 'ignore', 'under': 'ig nore'} In [7]: np.log(1./np.array(0)) Warning: divide by zero encountered in divide Out[7]: inf I have been using the orig_settings so that I can take over the control of this from the user and then set it back to how it was.
