Glorot uniform initializer, also called Xavier uniform initializer.
It draws samples from a uniform distribution within -limit, limit
where limit is sqrt(6 / (fan_in + fan_out))
where fan_in is the number of input units in the weight tensor
and fan_out is the number of output units in the weight tensor.
