# This test case is for 4d input gather operator.
# The input shape is [1,2,3,4] and this test produces output
# by referencing the data on axis 0 from the input to the indices value [0,0].
# In this case, the output shape changeds to [2,2,3,4] because it uses [0,0] indices on the 0 axis,
# and the data is configured as filling the 0th data of the input axis 0 twice.
