🐛 [Bug] TensorRT dependecy not installed when using Torch-TensorRT 1.4.0

[ivan94fi]

Bug Description

Installing the torch_tensorrt package version 1.4.0 from pip with pip install torch_tensorrt==1.4.0 does not install the required tensorrt package.

To Reproduce

Use pip install torch_tensorrt==1.4.0

Run this python line:

import tensorrt

Expected behavior

TensorRT should be installed as a dependecy of this package.

Environment

Build information about Torch-TensorRT can be found by turning on debug messages

• Torch-TensorRT Version (e.g. 1.0.0): 1.4.0
• PyTorch Version (e.g. 1.0): 2.0.1
• CPU Architecture: x86
• OS (e.g., Linux): Linux
• How you installed PyTorch (conda, pip, libtorch, source): installed by torch_tensorrt
• Build command you used (if compiling from source):
• Are you using local sources or building from archives:
• Python version: 3.10
• CUDA version:
• GPU models and configuration:
• Any other relevant information:

Additional context

The 1.3.0 wheels contain this line in the METADATA files:

Requires-Dist: torch (<1.14.0,>=1.13.0)
Requires-Dist: tensorrt (<8.6.0,>=8.5.1.7)

The 1.4.0 wheels contain only

Requires-Dist: torch (<2.1,>=2.0.1)

Is just installing tensorrt separately not working for you? We can fix this in the next release but we would not address this in 1.4.0 unless this causes actual issues using the library.

Installing tensorrt separately works, but it is not the expected workflow. If you do not plan to release a new patch version before the next release, I suggest to update the Prebuilt binaries and wheel files section in the readme: a simple note that suggests to install tensorrt separately would be enough.

By the way, maybe you are already aware of this, or even it was a design decision, but I think the cause of this behavior is that the setup.py file does not contain anymore the tensorrt package in the install_requires parameter of setup():

Tag 1.3.0:

TensorRT/py/setup.py

Line 378 in 8dc1a06

install_requires=["torch>=1.13.0,<1.14.0", "tensorrt>=8.5.1.7,<8.6.0"],

Tag 1.4.0:

TensorRT/py/setup.py

Lines 428 to 430 in 7d1d807

	install_requires=[
	"torch >=2.0.1,<2.1" if not LEGACY else "torch >=1.13.0,<2.0",
	],
