[noob question] Can I use HLS4ML to train a CNN on my PYNQ-ZU itself?

[Viggo-Avila]

apologies for the noob question :P.
I've been following the tutorials lately and it took me a whole day to understand part 1 and to get it working. I have a CNN model and I want to implement it on an FPGA. FIrst I want to do that by training it outside of the FPGA and then using hls4ml to convert it to FPGA. Then once that's done I wanted to use hls4ml to train the CNN on the FPGA itself.

hls4ml is for inference only, not for training on FPGAs.

Whaaat? Shucks, are there at least any known ways on how training on the FPGA can be achieved?

Try to find something in literature (on e.g., arxiv), most of the papers will mention the challenges with training on FPGAs and compromises this required. You'll find that it is mostly for very specific use-cases.
