`numpy:errstate`

source: /dev/numpy/build-install/usr/lib/python3.14/site-packages/numpy/__init__.py

Signature

class errstate ( ** kwargs )

Summary

Context manager for floating-point error handling.

Extended Summary

Using an instance of errstate as a context manager allows statements in that context to execute with a known error handling behavior. Upon entering the context the error handling is set with seterr and seterrcall, and upon exiting it is reset to what it was before.

Parameters

kwargs : {divide, over, under, invalid}: Keyword arguments. The valid keywords are the possible floating-point exceptions. Each keyword should have a string value that defines the treatment for the particular error. Possible values are {'ignore', 'warn', 'raise', 'call', 'print', 'log'}.

Notes

For complete documentation of the types of floating-point exceptions and treatment options, see seterr.

Examples

import numpy as np
olderr = np.seterr(all='ignore')  # Set error handling to known state.

✓

np.arange(3) / 0.
with np.errstate(divide='ignore'):
    np.arange(3) / 0.

✓

np.sqrt(-1)
with np.errstate(invalid='raise'):
    np.sqrt(-1)

✓

Outside the context the error handling behavior has not changed:

np.geterr()
olderr = np.seterr(**olderr)  # restore original state
