This provides a TensorBoard-native summary writing API that only depends on numpy and not any particular ML framework.

Accepts any value that can be converted to a `np.int64` scalar. wall_time: optional `float` seconds since the Unix epoch, representing the real-world timestamp for this data point. Defaults to None in which case the current time will be used. description: optional string description for this entire time series. This should be constant for a given tag; only the first value encountered will be used. datastepN) plugin_nametagrrrr) r_validate_scalar_shapenpfloat32int64timer emit_scalarscalars_metadata PLUGIN_NAME)r rrrrrvalidated_dataZvalidated_stepr r r add_scalarFszWriter.add_scalar) __name__ __module__ __qualname____doc__rrrrr$r r r rrs rcCs|jdkrtd||f|S)Nrz'Expected scalar value for %r but got %r)ndim ValueError)ndarraynamer r rrds   r) r(rnumpyrtensorboard.plugins.scalarrr!tensorboard.summaryrrrr r r rs   G
