from ray.rllib.utils.tf_run_builder import TFRunBuilder # create an instance of the TFRunBuilder run_builder = TFRunBuilder() # get a TensorFlow operation by name my_op = run_builder.get_op(sess=sess, name="my_op") # execute the operation result = sess.run(my_op)
from ray.rllib.utils.tf_run_builder import TFRunBuilder # create an instance of the TFRunBuilder run_builder = TFRunBuilder() # describe the input tensors input_tensors = {"input_a": input_a, "input_b": input_b} # describe the output tensors output_tensors = {"output_c": output_c, "output_d": output_d} # execute the graph with the inputs and outputs results = run_builder.run(sess=sess, inputs=input_tensors, outputs=output_tensors)In this example, we create an instance of the `TFRunBuilder` and use it to execute a TensorFlow graph with input and output tensors. We describe the input and output tensors using Python dictionaries and pass them to the `run()` method along with the TensorFlow session. The `run()` method returns a dictionary containing the output values. Overall, the `ray.rllib.utils.tf_run_builder.TFRunBuilder` is a useful tool for building and executing TensorFlow graphs in a concise and efficient manner.
