Based on logic presented by JerryMcDonald.dev in his answer. If reading this after comparison between Timestamp and datetime.date has been deprecated, you can apply numpy.datetime64 to your timestamp column to make it comparable with a datetime object:
datetime64[ns] is a general dtype, while <M8[ns] is a specific dtype. General dtypes map to specific dtypes, but may be different from one installation of NumPy to the next. On a machine whose byte order is little endian, there is no difference between np.dtype('datetime64[ns]') and np.dtype('<M8[ns]'):
