Create a TensorProto.


  • values: Values to put in the TensorProto.
  • dtype: Optional tensor_pb2 DataType value.
  • shape: List of integers representing the dimensions of tensor.
  • verify_shape: Boolean that enables verification of a shape of values.


A TensorProto. Depending on the type, it may contain data in the "tensor_content" attribute, which is not directly useful to Python programs. To access the values you should convert the proto back to a numpy ndarray with tensor_util.MakeNdarray(proto).

If values is a TensorProto, it is immediately returned; dtype and shape are ignored.


  • TypeError: if unsupported types are provided.
  • ValueError: if arguments have inappropriate values or if verify_shape is True and shape of values is not equals to a shape from the argument.

make_tensor_proto accepts "values" of a python scalar, a python list, a numpy ndarray, or a numpy scalar.

If "values" is a python scalar or a python list, make_tensor_proto first convert it to numpy ndarray. If dtype is None, the conversion tries its best to infer the right numpy data type. Otherwise, the resulting numpy array has a compatible data type with the given dtype.

In either case above, the numpy ndarray (either the caller provided or the auto converted) must have the compatible type with dtype.

make_tensor_proto then converts the numpy array to a tensor proto.

If "shape" is None, the resulting tensor proto represents the numpy array precisely.

Otherwise, "shape" specifies the tensor's shape and the numpy array can not have more elements than what "shape" specifies.
