model.uff converted by uff.from_tensorflow_frozen_model()
i seen log out have line: Converting Range_2 as custom op: Range
and many different custom op

code:

import tensorrt as trt

model_file = 'model.uff'

TRT_LOGGER = trt.Logger(trt.Logger.WARNING)

with trt.Builder(TRT_LOGGER) as builder, builder.create_network() as network, trt.UffParser() as parser:
	parser.register_input("fts_input_images", (1, 300, 300, 3))
	parser.register_output("final_fts_output_full")
	parser.parse(model_file, network)

log error:

[TensorRT] ERROR: UffParser: Validator error: Range_2: Unsupported operation _Range

how can i run custom op?
