SK-TDA4VM: Error running customized model script

Akaash Varatharajan

Part Number: SK-TDA4VM

I tried running the custom-model-tfl code from https://github.com/TexasInstruments/edgeai-tidl-tools/tree/master/examples/jupyter_notebooks. I'm getting an error at the following stage

I'm unable to open the shared object file. The snapshot is below

Can anyone help me figure out what am I doing wrong?

Hi Akaash,

Could you make sure the file /opt/jai_tidl_notebooks/tidl_model_import_tflite.so exists? If not, then this can be installed by installing PSDK RTOS and exporting TIDL_TOOLS_PATH to point to the tidl_tools folder: https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721E

Hi Akaash,

Before installing PSDK RTOS, could you also make sure you followed the following instructions by uncommenting and running export DEVICE=j7 before running setup.sh script: https://github.com/TexasInstruments/edgeai-tidl-tools#setup

The setup.sh script should install tidl. However, if setup.sh script is not setting up tidl, as an alternative:

Download and untar PSDK RTOS (no need to go through full SD card installation instructions)
Follow these instructions for pointing environment variable to tidl: https://github.com/TexasInstruments/edgeai-tidl-tools#advanced-setup-options

Hi Takuma,

I have executed the setup.sh script. My opt/ folder is empty. Do I need to manually setup the file structures in the opt folder? Is this the right way to verify tidl installation?

Hi Akaash,

Apologies for the late reply, I got pulled into other debug. I will get back to you tomorrow on setting up tidl. The setup.sh script should automatically download and set up the require dependencies.

In the meantime, could you let me know what Ubuntu version you are trying this on? We have validated these examples on Ubuntu 18.04.

Hi Akaash,

I think I know what is happening. The setup.sh script automatically installs and tidl, then exports TIDL_TOOLS_PATH to edgeai-tidl-tools/tidl_tools. A few other environment variables are set within the setup.sh script that are needed by the Jupyter notebook.

So in a single terminal, could you:

cd edgeai-tidl-tools
source ./setup.sh
cd edgeai-tidl-tools/examples/jupyter_notebooks
source ./launch_notebook.sh
Access notebooks from the provided links

Regards,

Takuma
