access2rohit opened a new issue #16216: Inconsistent behaviour nd.argmax against np.argmax when there are 'nans' in data URL: https://github.com/apache/incubator-mxnet/issues/16216 >>> import mxnet as mx >>> import mxnet.ndarray as nd >>> x = np.array([[1,5,3],[float('nan'), 2,6]]) >>> x array([[ 1., 5., 3.], [nan, 2., 6.]]) >>> y = nd.array(x) shape=(2, 3) [14:05:53] src/c_api/c_api.cc:190: MXNDArrayCreateExInt64 shape=2 >>> nd.argmax(y, axis=0) [0. 0. 1.] <NDArray 3 @cpu(0)> >>> nd.argmax(y, axis=1) [1. 2.] <NDArray 2 @cpu(0)> >>> import numpy as np >>> np.argmax(x, axis=0) array([1, 0, 1]) >>> np.argmax(x, axis=1) array([1, 0])
