How to Display Full NumPy Array Without Truncation

When printing NumPy arrays, you often encounter truncated representations. To display the entire array, utilize the numpy.set_printoptions function.

import sys
import numpy

# Set threshold to maximum size to disable truncation
numpy.set_printoptions(threshold=sys.maxsize)

Consider the following example:

>>> numpy.arange(10000)
array([   0,    1,    2, ..., 9997, 9998, 9999])

>>> numpy.arange(10000).reshape(250, 40)
array([[   0,    1,    2, ...,   37,   38,   39],
       [  40,   41,   42, ...,   77,   78,   79],
       [  80,   81,   82, ...,  117,  118,  119],
       ..., 
       [9880, 9881, 9882, ..., 9917, 9918, 9919],
       [9920, 9921, 9922, ..., 9957, 9958, 9959],
       [9960, 9961, 9962, ..., 9997, 9998, 9999]])

Now, using numpy.set_printoptions, we can print the full array without truncation:

numpy.set_printoptions(threshold=sys.maxsize)

print(numpy.arange(10000))
print(numpy.arange(10000).reshape(250, 40))

Output:

[0 1 2 ... 9997 9998 9999]
[[  0   1   2 ...  37  38  39]
 [ 40  41  42 ...  77  78  79]
 [ 80  81  82 ... 117 118 119]
 ...
 [9880 9881 9882 ... 9917 9918 9919]
 [9920 9921 9922 ... 9957 9958 9959]
 [9960 9961 9962 ... 9997 9998 9999]]
