Utilities for making TensorRT easier to use

trtutils

Utilities for enabling easier high-level usage of TensorRT in Python.

TRTEngine

The TRTEngine is a high-level abstraction allowing easy use of TensorRT engines through Python. Once an engine is built, it is simple and easy to use:

from trtutils import TRTEngine

engine = TRTEngine("path_to_engine")

inputs = read_your_data()

for i in inputs:
    print(engine.execute(i))

We also provide an abstraction for defining higher-level models. The TRTModel is designed to allow a user to define a pre and post processing step along with the engine to create an end-to-end inference object.

from trtutils import TRTModel

# scale some images down
def pre(inputs):
    return [i / 255 for i in inputs]

# access the output classes from object detection
def post(outputs):
    return [o[0][0] for o in outputs]

model = TRTModel("path_to_engine", pre, post)

inputs = read_your_data()

for i in inputs:
    print(model(i))
