I had this expression: RuntimeWarning: invalid value encountered in log Entry point for launching an IPython kernel. while trying this: IN1: import numpy as np import pandas as pd from pandas_datareader import data as wb import matplotlib.pyplot as plt. IN2:, np .log( 0.6*c) and np.log(a**2) in the for loop with: np.random.normal() you will get random numbers at this distribution, whose values will be negative numbers. That’s why np.log() will drop up the error message: RuntimeWarning: invalid value encountered in log .

Mathematically speaking, log (0) is undefined. The standard behavior for most computer languages, such as matlab, is to return -inf. Some languages, such as C++ will return -inf and raise a div by zero exception. Given that it’s just a warning you could opt to ignore or suppress the warning and move on.

python – invalid value encountered in log , RuntimeWarning: invalid value encountered in log log = np.sum(np.nan_to_num (-y*np. log (a+ 1e-7)-(1-y)*np. log (1-a+ 1e-7))). python – invalid value encountered in log ,You probably still have negative values inside the log , which gives nan with real numbers. a and y should represent probability between 0 to 1, RuntimeWarning: invalid value encountered in log log = np.sum(np.nan_to_num(-y*np. log (a+ 1e-7)-(1-y)*np. log.
4 Answers4. Your problem is caused by the NaN or Inf elements in your out_vec array. You could use the following code to avoid this problem: if np.isnan (np.sum (out_vec)): out_vec = out_vec [~numpy.isnan (out_vec)] # just remove nan elements from vector out_vec [out_vec > 709] = 709 …
