TypeError: catching classes that do not inherit from BaseException is not allowed

See original GitHub issue

I upgraded my python3 version on my MacBook pro to 3.7.7, and now distributed is not able to serialize/deserialize.

Thanks for raising an issue @muammar. This error: TypeError: unpackb() got an unexpected keyword argument 'strict_map_key' is coming from msgpack. What version of msgpack do you have installed? We recently bumped the minimum supported version to msgpack==0.6.0, which should have the 'strict_map_key' keyword argument
