reverse proxy and mDNS
1) Deal with the use of only port 80 and 43 on most public networks with a reverse proxy

That reminds me, in https://github.com/bshambaugh/BlinkyProject/blob/remoteSigner/edgeDevices/ESP32-testing/include/websocketserver_config.h I have the IP address of the laptop assigned by the router hardcoded which I can discover by hostname -I on the laptop. Recompiling the ESP32 with the new IP address when I move to a new network like 192.168.1.29 (or even if the router reassigns it .... occasionally locally I go from 10.0.0.4 to 10.0.0.5 and back again) is a pain. I think this is a different issue though....I just need to somehow give my devices unique identifiers, call out to them through some sort of broadcast scheme and pull down their assigned IP addresses.
lots to think about, thanks for your help so far. (Find the IP address

RNN shape?
I worked with this model during the EthDenver https://github.com/spro/char-rnn.pytorch . I did not manage to get the right shape for https://github.com/zkonduit/pyezkl/tree/main/examples/tutorial . (loading the model to convert to *.onnx)
I learned a bit about ML though. :P

likely shape for ONNX for RNN
def main():
torch_model = Circuit()
# Input to the model
shape = [3, 2, 2] /// change to [batch_size, seq_len, input_size]
x = 0.1*torch.rand(1,*shape, requires_grad=True)
y = 0.1*torch.rand(1,*shape, requires_grad=True)
torch_out = torch_model(x, y)
# Export the model
torch.onnx.export(torch_model, # model being run
(x,y), # model input (or a tuple for multiple inputs)

How to deploy your own other models
Read the documentation
Read through the AXera Pulsar toolchain guide to learn how to convert a custom onnx model into the Joint model used in AX620.
Inserting Post-Processing Code
The model inference in ax-pipeline is basically a standard operation, and pre-processing is not something that needs to be configured in the code.

Update Log
2023-01-16 Added YoloV8, please refer to ModelZoo for details.
2022-12-29 Added sample_v4l2_user_ivps_joint_vo for direct input of NV12 data, if the user has access to NV12 data. Modified the value of enum class SAMPLE_RUN_JOINT_MODEL_TYPE to meet the growing list of model support.
2022-12-26 Added sample code for rtsp input sample_rtsp_ivps_joint_vo
