How to fix NumPy timedelta64 TypeError: Invalid datetime unit "min" in metadata

Problem:

You want to construct a NumPy timedelta64 from a value in minutes using

example.py

np.timedelta64(1, 'min')

np.timedelta64(1, 'min')

but you see an error message like

output.txt

Traceback (most recent call last):
    File "test.py", line 3, in <module>
        delta = np.timedelta64(1, 'min')
TypeError: Invalid datetime unit "min" in metadata

Traceback (most recent call last):
    File "test.py", line 3, in <module>
        delta = np.timedelta64(1, 'min')
TypeError: Invalid datetime unit "min" in metadata

Solution

numpy uses m as specifier for minutes, not min! Change your code to

example_fixed.py

np.timedelta64(1, 'm')

np.timedelta64(1, 'm')
