Numpy random choice in Python GeeksforGeeks
Example 1 In this example we can see that by using choice method we are able to get the random samples of numpy array it can generate uniform or non uniform samples by using this method Python3 import numpy as np import matplotlib pyplot as plt gfg np random choice 13 5000 count bins ignored plt hist gfg 25 density True
How to Use Numpy Random Choice Sharp Sight, So by running np random choice this way it will create a new numpy array of values from 0 to 9 and pass that as the input to numpy random choice This is essentially a shorthand way to both create an array of input values and then select from those values using the NumPy random choice function
Python About how numpy random choice works Stack Overflow
Numpy problems or not Your code seems fine including your use of np random choice One possible spot of confusion you might be having relates to the default value of the replace parameter replace defaults to True so you don t need to explicitly pass replace True to choice in code block 1 Aside from that very minor issue there s no glaring problems with your code
