解决方法
def default(self, obj):
if isinstance(obj, (numpy.int_, numpy.intc, numpy.intp, numpy.int8,
numpy.int16, numpy.int32, numpy.int64, numpy.uint8,
numpy.uint16,numpy.uint32, numpy.uint64)):
return int(obj)
elif isinstance(obj, (numpy.float_, numpy.float16, numpy.float32,
numpy.float64)):
return float(obj)
elif isinstance(obj, (numpy.ndarray,)): # add this line
return obj.tolist() # add this line
return json.JSONEncoder.default(self, obj)
成功解决！
