Is mx.nd.array thread safety?

Assume that one thread is calling mx.nd.array to create NDarray, and another thread is calling mx.nd.array too. Is it safe? I realize that autograd is not thread safe, but I wonder that whether it is safe for other API.

MXNet is in general not thread safe, so the creation and deletion of ndarrays must happen in the same thread. You can also find some more information in this thread:
