Cannot print numpy arrays with logging module

This snippet doesn’t print anything:

import logging
import numpy as np

logging.info(np.eye(4))

# this doesn't work either
logging.info('matrix', np.eye(4))

But it works fine with native print:

import logging

print(np.eye(4))

[[1. 0. 0. 0.]
 [0. 1. 0. 0.]
 [0. 0. 1. 0.]
 [0. 0. 0. 1.]]

>Solution :

I think the issue is with your logging level.

If I try logging.warning(np.eye(4)), I get an output in my console.

Try the following code:

import logging
import numpy as np

# Fix logging level issue
logging.getLogger().setLevel(logging.INFO)

logging.info(np.eye(4))

Output:

INFO:root:[[1. 0. 0. 0.]
 [0. 1. 0. 0.]
 [0. 0. 1. 0.]
 [0. 0. 0. 1.]]
