Tao-converter doesn't convert ".etlt" to ".engine"

mericgeren · October 2, 2023, 1:58pm

• Hardware: Nano

• Network Type: FaceNet

• TLT Version: N/A(I am only using tao-converter)

• Training spec file: N/A (I have pretrained models with “.etlt” extentions)

• JetPack Version: 4.6.4

• How to reproduce the issue ?

Follow this guide:

Select and download the “tao-converter” for Jetpack 4.6 from the table under the title “Prerequistes”.
Create a folder for tao-converter right under ~ named “tcnv”
Open the downloaded tao-converter zip file with “Files” application.
Open the folder you have just created with another window of the “Files” application.
Drag and drop the contents of the zip file one by one from the window and drop them into the other window on which the directory you have created have opened.
Open the terminal and move right under ~ directory.
Enter these commands:

git clone -b release/tao3.0_ds6.0.1 https://github.com/NVIDIA-AI-IOT/deepstream_tao_apps.git
sudo apt-get install git-lfs
git lfs install
git lfs install --skip repo
git lfs install --skip-repo
cd deepstream_tao_apps
git lfs pull
export TAO_CONVERTER=/home/User/tcnv/tao-converter
export MODEL_PRECISION=fp16
sudo ./download_models.sh
export CUDA_VER=10.2
make

Check “models/faciallandmark” if there is any tensorrt engine file have been created.
See there isn’t any tensorrt engine file is present inside the directory.

Thanks in advance for all the help you offer.

According to https://github.com/NVIDIA-AI-IOT/deepstream_tao_apps/blob/release/tao3.0_ds6.0.1/download_models.sh, this script only downloads models.
It does not convert etlt model to tenosrrt engine.
Did you download tao-converter and run command to generate tensorrt engine?

mericgeren · October 3, 2023, 6:26am

I have downloaded and tested with /home/User/tcnv/tao-converter -h command.

I am fooled by this line in the readme:

Please run the following script to download pre-trained models and generate GazeNet and Gesture engines with tao-converter tool.

When i checked Gesture model folder, there were only ".etlt and calibration files.

I am sorry for taking your time and thank you for your explanation.

P.S. If you don’t mind could you explain how can i use tao-converter to generate tensorrt engine for “heartrate” and “facenet” models please?

Morganh · October 3, 2023, 2:06pm

Refer to https://github.com/NVIDIA-AI-IOT/deepstream_tao_apps/blob/master/build_triton_engine.sh.

Thank you for the link.

After referring to the link and trying the command:

/home/User/tcnv/tao-converter -k nvidia_tlt -t int8 -c models/faciallandmark/fpenet_cal.txt -b 1 -d 3,416,736 -e models/faciallandmark/facenet.etlt_b1_gpu0_int8.engine models/faciallandmark/facenet.etlt

I got this output:

Even though i couldn’t see any error or any message mentioning a failure, when i checked the models/faciallandmark directory, i saw that it didn’t create the engine file. Could you offer your guidance please?

Morganh · October 4, 2023, 4:00pm

Please check if there is write access. Suggest you to change to another folder.

mericgeren · October 5, 2023, 9:28am

Thanks, for the suggestion. After solving the write access issue, i have managed to create the engine file for faciallandmarks. But, i couldn’t found how to do the conversion for heartrate after refering to link. I have tried the command, referring here:

/home/User/tcnv/tao-converter -k nvidia_tlt -t int8 -p input,1x3x36x36,1x3x72x72,1x3x72x72 -e models/heartrate/heartrate.etlt_b16_gpu0_fp16.engine models/heartrate/heartrate.etlt

But, i got this output:

Could you offer your advice please?

Morganh · October 5, 2023, 3:11pm

Glad to know fpenet works now.

Morganh · October 5, 2023, 3:16pm

For heartratenet, please run

    tao-converter -k nvidia_tlt -t fp16 \
        -p appearance_input:0,1x3x72x72,1x3x72x72,2x3x72x72 \

        -e model.engine \
        model.etlt

mericgeren · October 6, 2023, 7:09am

Thank you for your kind advice.

After running this command for heartratenet:

home/User/tcnv/tao-converter -k nvidia_tlt -t fp16 -p appearance_input:0,1x3x72x72,1x3x72x72,2x3x72x72 -p motion_input:0,1x1x3x72x72,1x1x3x72x72,1x2x3x72x72 -e heartrate.etlt_b16_gpu0_fp16.engine heartrate.etlt

I managed to create the engine and this is the output i got:

Thank you so much for all the help you have offered.

P.S. I need to add that, there was something quirky about the conversion. As you might notice from the command i have used, i had to add an extra dimension to input shapes of motion_input:0. Since, when i run the code, it tends to ignore the first layer in the shapes of motion_input:0.
