Args:
model_path: Path to TF-Lite Flatbuffer file.
model_content: Content of model.
experimental_delegates: Experimental. Subject to change. List of
[TfLiteDelegate](https://www.tensorflow.org/lite/performance/delegates)
objects returned by lite.load_delegate().
num_threads: Sets the number of threads used by the interpreter and
available to CPU kernels. If not set, the interpreter will use an
implementation-dependent default number of threads. Currently, only a
subset of kernels, such as conv, support multi-threading. num_threads
should be >= -1. Setting num_threads to 0 has the effect to disable
multithreading, which is equivalent to setting num_threads to 1. If set
to the value -1, the number of threads used will be
implementation-defined and platform-dependent.
experimental_op_resolver_type: The op resolver used by the interpreter. It
must be an instance of OpResolverType. By default, we use the built-in
op resolver which corresponds to tflite::ops::builtin::BuiltinOpResolver
in C++.
experimental_preserve_all_tensors: If true, then intermediate tensors used
during computation are preserved for inspection, and if the passed op
resolver type is AUTO or BUILTIN, the type will be changed to
BUILTIN_WITHOUT_DEFAULT_DELEGATES so that no Tensorflow Lite default
delegates are applied. If false, getting intermediate tensors could
result in undefined values or None, especially when the graph is
successfully modified by the Tensorflow Lite default delegate.
Raises:
ValueError: If the interpreter was unable to create.
