+## Operators that does not work with hybridize
+
+If you want to hybridize your model, you must use `F.some_operator` in your 'hybrid_forward' function, F will be 'mxnet.nd' before you hybridize and 'mxnet.sym' after hybridize. While most APIs are the same in NDArray and Symbol,  there are some differences. Writing `F.some_operator` and call `hybridize` may not work all the time.
