It draws samples from a truncated normal distribution centered on 0
with stddev = sqrt(2 / (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.
initializer_glorot_normal(seed = NULL)Integer used to seed the random generator.
