fpgaRT.execute hangs

Hi,

My platform is AWS, and I was going through the jupyter notebook tutorial, image_classification_tensorflow.ipynb.

I realized that the execution hangs at the following step: Step 9. Write optimized micro-code to the xDNN Processing Engine on the FPGA.

I assume it's not supposed to take minutes for running inferences (rather it should take a few milliseconds I guess).

The following is my log on the terminal session that I opened the jupyter:

xclProbe found 1 FPGA slots with xocl driver running
CL_PLATFORM_VENDOR Xilinx
CL_PLATFORM_NAME Xilinx
CL_DEVICE_0: 0x980df20
CL_DEVICES_FOUND 1, using 0
loading ../overlaybins/aws/overlay_3.xclbin
This AFI already loaded. Skip reload!
Successfully skipped reloading of local image.
[XBLAS] kernel0: kernelSxdnn_0
[XDNN] loading xclbin settings from ../overlaybins/aws/overlay_3.xclbin.json
[XDNN] using custom DDR banks 2

[XDNN] kernel configuration
[XDNN] num cores : 1
[XDNN] dsp array width : 56
[XDNN] img mem size : 5 MB
[XDNN] version : 2.3
[XDNN] 8-bit mode : 0
[XDNN] Max Image W/H : 1023
[XDNN] Max Image Depth : 4095
[XDNN] Max Filter Depth : 0

Is there anybody who has clues on this? Thanks!

Resolved. Should have used ml suite AMI instead of F1's default AMI.

Re: fpgaRT.execute hangs

Hi,

Does the Jupyter notebook cell ever finish executing? Or is there still a * displayed?

What input size are you running?

We recently saw a hang with 11x11x12 input, due to a bug in the runtime, which we will fix in the next release.
