'dict' object has no attribute 'version'` loading the network 1.6.1 from json #401

Closed Xevib closed 5 years ago

Xevib commented 5 years ago

If I load a network from the version 1.6.1 stored on a JSON fails on this 

pandapower.from_json(s)

At this point the net variable is a dict and crashes with the error AttributeError: 'dict' object has no attribute 'version'

That is strange, it shouldn't come out as a dictionary. There are tests that load networks saved in older versions to check backwards compatibility: https://github.com/e2nIEE/pandapower/tree/develop/pandapower/test/test_files/old_versions

Can you check if you can load the file that is saved there with 1.6.1?
