INVALID_ARGUMENT: getPluginCreator could not find plugin CustomEmbLayerNormPluginDynamic version 1

Opened this issue 4 years ago · 5 comments

Hi @TrojanXu, am trying to deploy the BERT TensorRT model with Triton following your steps but getting the below error:

Previously I built and copied the plugins to /opt/tritonserver
export LD_PRELOAD=/opt/tritonserver/libbert_plugins.so:/opt/tritontserver/libcommon.so

then I ran the triton server
sudo docker run --gpus all --rm --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -p443:443 -p8080:8080 -v /home/triton_server/docs/examples/model_repository/:/models nvcr.io/nvidia/tritonserver:20.03.1-py3 tritonserver --model-repository=/models

Error:

Some recommendations on how to fix this issue or if there is a recent version of the SW that simplified the deployment?

Versions used:
TensorRT: release 6.0
Triton docker image: tritonserver:20.03.1-py3

Hi Vilmara, how you pass LD_PRELOAD to tritonserver inside the container?

Hi @TrojanXu, I have tried several methods without success:

Method 1: -e LD_PRELOAD=/opt/tritonserver/libbert_plugins.so:/opt/tritontserver/libcommon.so
sudo docker run --gpus all --rm --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -p443:443 -p8080:8080 -v /home/triton_server/docs/examples/model_repository/:/models -e LD_PRELOAD=/opt/tritonserver/libbert_plugins.so:/opt/tritontserver/libcommon.so nvcr.io/nvidia/tritonserver:20.03.1-py3 tritonserver --model-repository=/models

Method 2: once inside the docker export LD_PRELOAD=/opt/tritonserver/libbert_plugins.so:/opt/tritontserver/libcommon.so
sudo docker run --gpus all --rm --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -p443:443 -p8080:8080 -v /home/triton_server/docs/examples/model_repository/:/models nvcr.io/nvidia/tritonserver:20.03.1-py3

method 2 does nothing just starts the docker image and exits immediately without errors:

Further questions:
1- Do you recommend to try with the latest SW version, if so, which one?
2- What docker image should I use?, I see in your Triton presentation you used nvcr.io/nvidia/tensorrtserver instead of nvcr.io/nvidia/tritonserver

Answer 3 · 2020-10-16T15:01:47.000Z

Yes, my question is how you put file libbert_plugins.so to /opt/tritonserver/ inside the docker container? Have you modified nvcr.io/nvidia/tensorrtserver image? From the command you provided, I only see you were using unmodified image nvcr.io/nvidia/tritonserver:20.03.1-py3 from ngc. But have you put libbert_plugins.so itself into the docker image?

Answer 4 · 2020-10-16T22:21:23.000Z

hi @TrojanXu, what is the best way to put the files libbert_plugins.so and libcommon.so to /opt/tritonserver/ inside the docker container?. I modified the nvcr.io/nvidia/tensorrtserver image editing the Dockerfile as shown below but I got errors rebuilding the image:

Dockerfile addition:

RUN cp /opt/tensorrtserver/libbert_plugins.so /opt/tensorrtserver/
RUN cp /opt/tensorrtserver/libcommon.so /opt/tensorrtserver/
ENV LD_PRELOAD /opt/tensorrtserver/libbert_plugins.so:/opt/tensorrtserver/libcommon.so

Error when building the image:

cp: cannot stat '/opt/tensorrtserver/libbert_plugins.so': No such file or directory
The command '/bin/sh -c cp /opt/tensorrtserver/libbert_plugins.so /opt/tensorrtserver/' returned a non-zero code: 1

One best way is to launch this docker container interactively, and pass lib directory into the container via '-v' option. Actually this the way described in the method 2 you mentioned. But you need to add some additional flags, the full cmd should be,
sudo docker run --gpus all --rm -it --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -p443:443 -p8080:8080 -v /home/triton_server/docs/examples/model_repository/:/models -v /path/to/your/libs/:/path/inside/container nvcr.io/nvidia/tritonserver:20.03.1-py3 bash
Then you can launch tritonserver manually inside the container by,
LD_PRELOAD=/path/inside/container/libxxx.so trtserver tritonserver --model-repository=/models
