x Tensor or variable.
pool_size tuple of 2 integers.
strides tuple of 2 integers.
padding string, "same" or "valid".
data_format string, "channels_last" or "channels_first".
pool_mode string, "max" or "avg".

A tensor, result of 2D pooling.

ValueError if data_format is neither "channels_last" or "channels_first".
ValueError if pool_size is not a tuple of 2 integers.
ValueError if strides is not a tuple of 2 integers.
ValueError if pool_mode is neither "max" or "avg".
