npzwrite cannot write Dict in julia 0.6

[algorithmx]

It seems that the function overload at line 276 in NPZ.jl has not been recognized because the error indicates a call to line 272 (... src/NPZ.jl:272).

My idea to fix it is simply adding a new function called "npzwrite_dict" ... or changing the name of that function. But I am completely new to GitHub and don't know how to update it ...

Any helps ?

Walk-around:

using PyCall @pyimport numpy as np np.savez_compressed("test.npz".en=dict["en"])
