- class InferenceMemory(*, count=None, tensors=None)[source]
Bases:
morpheus.messages.memory.tensor_memory.TensorMemoryThis is a base container class for data that will be used for inference stages. This class is designed to hold generic tensor data in cupy arrays.
- Attributes:
- tensor_names
Methods
get_input(name)Get the tensor stored in the container identified by
name.get_tensor(name)Get the Tensor stored in the container identified by
name.Get the tensors contained by this instance.
has_tensor(name)Returns True if a tensor with the requested name exists in the tensors object
set_input(name, tensor)Update the input tensor identified by
name.set_tensor(name, tensor)Update the tensor identified by
name.set_tensors(tensors)Overwrite the tensors stored by this instance.
- get_input(name)[source]
Get the tensor stored in the container identified by
name. Alias forInferenceMemory.get_tensor.- Parameters:
- namestr
Key used to do lookup in inputs dict of the container.
- Returns:
- cupy.ndarray
Inputs corresponding to name.
- Raises:
- KeyError
If input name does not exist in the container.
- get_tensor(name)[source]
Get the Tensor stored in the container identified by
name.- Parameters:
- namestr
Tensor key name.
- Returns:
- cupy.ndarray
Tensor.
- Raises:
- KeyError
If tensor name does not exist in the container.
- get_tensors()[source]
Get the tensors contained by this instance. It is important to note that when C++ execution is enabled the returned tensors will be a Python copy of the tensors stored in the C++ object. As such any changes made to the tensors will need to be updated with a call to
set_tensors.- Returns:
- typing.Dict[str, cp.ndarray]
- has_tensor(name)[source]
Returns True if a tensor with the requested name exists in the tensors object
- Parameters:
- namestr
Name to lookup
- Returns:
- bool
True if the tensor was found
- set_input(name, tensor)[source]
Update the input tensor identified by
name. Alias forInferenceMemory.set_tensor- Parameters:
- namestr
- tensorcupy.ndarray
Key used to do lookup in inputs dict of the container.
Tensor as a CuPy array.
- set_tensor(name, tensor)[source]
Update the tensor identified by
name.- Parameters:
- namestr
- tensorcupy.ndarray
Tensor key name.
Tensor as a CuPy array.
- Raises:
- ValueError
If the number of rows in
tensordoes not matchcount
- set_tensors(tensors)[source]
Overwrite the tensors stored by this instance. If the length of the tensors has changed, then the
countproperty should also be updated.- Parameters:
- tensorstyping.Dict[str, cupy.ndarray]
Collection of tensors uniquely identified by a name.
