Can't perform NL (Non-Linear) model training on 3.1.0

[AnkhInnovationsLLC]

Hello,

Seems like something is wrong with NL model training using the tools provided for the XVF3800 while connected with the "Local Device" pathway as described in the user guide. This is a UA build at 16 kHz.

Code: Select all

kevin@Kevin-Parkers-MacBook-Pro mac_x86_64 % ./xvf_host nl_model_training /System/Volumes/Data/Users/kevin/Downloads/XVF3800-Software_v3_1_0/xvf3800_source_240205_204034/sources/xvf_tools.py
Command NL_MODEL_TRAINING does not exist.
Maybe you meant BLD_MODIFIED.

Was it the command renamed? Because there isn't any such mention in the source for the device itself

Code: Select all

kevin@Kevin-Parkers-MacBook-Pro sources % grep -iR "NL_MODEL_TRAINING" ./

.//xvf_tools.py:    "nl_model_training":        NL_MODEL_GEN_SCRIPTS_DIR + "nl_model_training.py",
.//xvf_tools.py:    "remote_nl_model_training": NL_MODEL_GEN_SCRIPTS_DIR + "remote_nl_model_training.py",

Is this an Raspberry Pi only tool or should local devices be supported?

Hey there,

I think you've got the python and xvf_host binary the other way around. xvf_tools.py needs a path to xvf_host as the script uses it inside. So you'll need to do:

Code: Select all

python3 xvf_tools.py nl_model_training <host_app> [--protocol {i2c,spi,usb}]

You can find more info in the 3800 docs https://www.xmos.com/documentation/XM-0 ... near-model

Yep that was it... Thank you @upav
