chainer.testing.assert_allclose(x, y, atol=1e-05, rtol=0.0001, verbose=True)[source]

Asserts if some corresponding element of x and y differs too much.

This function can handle both CPU and GPU arrays simultaneously.

  • x – Left-hand-side array.

  • y – Right-hand-side array.

  • atol (float) – Absolute tolerance.

  • rtol (float) – Relative tolerance.

  • verbose (bool) – If True, it outputs verbose messages on error.
