Intel FPGA AI suite accuracy drop

Hello, I'm using Intel FPGA AI 2023.2 on ubuntu 20.04 host computer and trying to infer a custom CNN in a Intel Arria 10 SoC FPGA. The CNN was trained with TensorFlow and the accuracy is 98.89% acr...

Hi,


May I know if you are to try different .arch on the FPGA bitstream?

    Hello @JohnT_Intel

    I prefer to manage the issues in different threads as they seem to have different root causes.

    It has already been tested with the four example architectures provided in the Intel FPGA AI suite, and the same accuracy drop was observed.

    When running the graph on the ARM CPU, the accuracy is acceptable. It appears to be a potential issue with dla compiler and the dimensions in the dense layer.
