Documentaion bug: mxnet.test_utils.assert_almost_equal_with_err doesn't accept threshold as an input

[DNXie]

Description

This is a documentation bug. The Parameter section of the documentation of mxnet.test_utils.assert_almost_equal_with_err stated the parameter threshold. But it is not in the siganture and not accepted by the API, and passing it throws exception.

Link to the doc: https://mxnet.apache.org/versions/1.6/api/python/docs/api/mxnet/test_utils/index.html#mxnet.test_utils.assert_almost_equal_with_err

Error Message

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: assert_almost_equal_with_err() got an unexpected keyword argument 'threshold'

To Reproduce

import mxnet
import numpy as np
a = np.ndarray(shape=(2,2), dtype=float)
b = np.ndarray(shape=(2,2), dtype=float)
mxnet.test_utils.assert_almost_equal_with_err(a,b,threshold=None)
