I am using numpy.log10 to calculate the log of an array of probability values. There are some zeros in the array, and I am trying to get around it using. result = numpy.where(prob > 0.0000000001, numpy.log10(prob), -10) However, RuntimeWarning: divide by zero encountered in log10 still appeared and I am sure it is this line caused the warning.
8/16/2016 · ./lstm_text_generation.py:66: RuntimeWarning: divide by zero encountered in log preds = np. log (preds) / temperature When epoch 3 started, loss was somewhere between 6.0 and 9.0. It slowly decreased from there, reaching 5.0 at around 70% mark of the epoch (when I.

The warning originates from np. log (yp) when yp==0 and in np. log (1 – yp) when yp==1. One option is to filter out these values, and not to pass them into np. log . The other option is to add a small constant to prevent the value from being exactly 0 (as suggested in one of the comments above), 1/22/2014 · Here’s the output from running the script file: platform linux python sys.version_info(major=3, minor=3, micro=3, releaselevel=’final’, serial=0) 64 bit True pint 0.5.dev0 numpy 1.8.0 temp.py:13: RuntimeWarning: divide by zero encountered in log np. log (x / y) temp.py:15: RuntimeWarning: divide by zero encountered in log np. log (0.5 * ureg.dimensionless) temp.py:16: RuntimeWarning : divide .
RuntimeWarning : divide by zero encountered in double_scalars. and in another line two errors: RuntimeWarning : divide by zero encountered in double_scalars. RuntimeWarning : invalid value encountered in arcsin. I found it might be problem with float values, but im not sure about it and im typing it here for looking yours help. 🙂 Here is the code:, 7/3/2014 · Try to increase the internal precision by providing dtype=np.float64 as an argument to the LdaModel (default is np.float32). This will prevent the model from truncating very low values to .0, resulting in np. log (.0) = -inf, which then triggers this warning.
