Thanks for reporting this! Would you like to submit a pull request to fix the problem? We can change the code to normal(0, math.sqrt(lr), shape=weight.shape, dtype=weight.dtype, ctx=weight.context)

Steps to reproduce
simply call SGLD's update method.
What have you tried to solve it?
change the line
weight.shape, weight.context)
(https://github.com/apache/incubator-mxnet/blob/9ae63d16b600b52d7ec6c83cdffe427a27583fee/python/mxnet/optimizer.py#L767)into
weight.shape, ctx=weight.context
as the position of weight.context is belong todtype
