Unary op support from UFFParser issue under TensorRT 4.0

Software
Jetpack 3.3 with TensorRT 4.0

We are converting a network(which has PRELU layer included, abs opt is required for PRELU) from uff with giexec, this issues stop us:

UFFParser: Parser error: resnet_v1_50/prelu0/Abs: Unary not supported for other non-constant node

Also tried a script (scripts/convert_plan.py) from official tensorflow to tensorrt python project:

Still got similar error:

UFFParser: Parser error: resnet_v1_50/prelu0/Abs: Unary not supported for other non-constant node

From tensorrt 4.0 document, abs operation is support for TensorFlow, looks like conflict with the issue I have met. Seems like this issue comes from “/usr/lib/aarch64-linux-gnu/libnvparsers.so.4.1.3”

Hi,

This is a known issue and our internal team is working on this.
Will update information with you later.

Thanks.

HI, any update on this?

Hi,

This issue is fixed in the uff 0.6.1, which is included into TensorRT5.1.
TensorRT5.1 is not available for Jetson yet but the package for x86 environment is released.

Thanks.
