Hi Shuai,

can you try to run the "sudo" command with "-H" option, like this:

sudo -H pip3 install -e .

Hi Shuai,

PyTIOVX module requires Python 3.5.2 or later. Can you run the command like:

python3 vx_tutorial_graph_image_gradients_pytiovx_uc.py

Regards,

Yordan

then i add (export VISION_APPS_PATH="/home/super/psdk_rtos_auto_j7_06_01_00_15/vision_apps:$VISION_APPS_PATH")

in ~/.bashrc and source ~/.bashrc but not done.

Hi Shuai,

can you try just this:

export VISION_APPS_PATH="/home/super/psdk_rtos_auto_j7_06_01_00_15/vision_apps

in the console before running the script and see if it works?

Regards,

Yordan

Hi Shuai,

VISION_APPS_PATH variable is not visible by the script, because you run it with 'sudo'. If you run it like this:

sudo -E python3 vx_tutorial_graph_image_gradients_pytiovx_uc.py

it will probably work ('-E' tells sudo to preserve the environment), but you should be able to run the script without "sudo" anyway and it is quite strange that it fails.

Can you try the following commands (this will uninstall the 'tiovx' module and install it again):

sudo -H pip3 uninstall tiovx
cd ~/psdk_rtos_auto_j7_06_01_00_15/tiovx/tools/PyTIOVX
sudo -H python3 -m pip install -e .
cd ~/psdk_rtos_auto_j7_06_01_00_15/tiovx/tutorial/ch03_graph
export VISION_APPS_PATH=~/psdk_rtos_auto_j7_06_01_00_15/vision_apps/
python3 vx_tutorial_graph_image_gradients_pytiovx_uc.py

and see if it works?

Hi :Yordan

is this Successful？ vx_tutorial_graph_image_gradients_pytiovx_uc and vx_tutorial_graph_image_gradients_pytiovx_uc_img.txt are created. other files in psdk_rtos_auto_j7_06_01_00_15\tiovx\tutorial\ch03_graph Is iwritten by hand?(vx_tutorial_graph_image_gradients_pytiovx_uc vx_tutorial_graph_image_gradients_pytiovx_uc.h vx_tutorial_graph_image_gradients_pytiovx_uc.c vx_tutorial_graph_image_gradients_pytiovx.c vx_tutorial_graph_image_gradients.c )

Hi Shuai,

it looks successful! Check psdk_rtos_auto_j7_06_01_00_15/vision_apps/apps/vx_tutorial_graph_image_gradients_pytiovx_uc folder for the generated files.

Hi Shuai,

it creates the following files:
