microraiden.client.client Client returns ValueError: No matching functions found

I have following code on both kovan and mainnet:

with Client(privkey, 
channel_manager_proxy = channel_manager_proxy
) as client:

    channel = client.get_suitable_channel(receiver, 10)

I am getting following error:

Looks like you're using an outdated version of µRaiden. We'll be releasing a new version soon that improves usability a lot and fixes stuff like this. Meanwhile, please base your work on master.
