TypeError: the JSON object must be str, not 'bytes' when using py2cytoscape.cyrest.cyclient()

[yangli-ai]

Any operations with py2cytoscape.data.cyrest_client.CyRestClient works fine with me. But any operations with py2cytoscape import cyrest.cyclient() always returns the same error: for example, try commands: from py2cytoscape import cyrest csc=cyrest.cyclient() csc.status() # return CyREST online! csc.version() # return cytoscapeVersion 3.7.1 apiVersion v1 csc.node.list() # this command and other commands return the same error

This is a behavior of python 3.5 or earlier. Starting python 3.6 json.loads can accept byte strings. I'll see if I can make a pull request to fix it for you.

[zachary822]

Even though this issue doesn't exist after python 3.6, I feel the changes in #84 should make the code a bit more clear.

Thanks. That is the problem.
