Python error when calling NumPy from class method with map

Question

The following code throws me the error:

Traceback (most recent call last):
  File \"\", line 25, in 
    sol = anna.main()
  File \"\", line 17, in         


        

Answer 1

As others have noticed, this boils down to the fact that np.sqrt(7131 ** 5) works but np.sqrt(7132 ** 5) returns an error:

import numpy as np

print(np.sqrt(7131 ** 5))
print(np.sqrt(7132 ** 5))

# 4294138928.9
Traceback (most recent call last):
  File "main.py", line 4, in 
    print(np.sqrt(7132 ** 5))
AttributeError: 'int' object has no attribute 'sqrt'

Since np.sqrt docs don't mention any bounds on the argument, I'd consider this a numpy bug.
