New submission from Jason Hihn <ja...@apkudo.com>:
Given this traceback:
File
"/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/encoder.py",
line 184, in default
raise TypeError(repr(o) + " is not JSON serializable")
TypeError: 7.0374198 is not JSON serializable
It would actually be better to have the error reported as type(o)+ " is not
JSON serializable." because at first glance, 7.0374198 *is* serializable. In
this specific case, the issue can be fixed by attempting to serialize float(o),
because it is a ndarray. Maybe there's a better way to do numpy types or some
kind of automatic conversion but for now, this is only a request to alter the
message, I'd hope to something like:
repr(o) + " of type " + type(o) + " is not JSON serializable"
It's it's really more about the type rather than the value being serialized.
