IP definition not found for VLNV

[maires1306]

Hi, everyone!

I'm trying to build finn_examples network resnet50_w1a2 but I'm getting: ERROR: [BD 5-390] IP definition not found for VLNV: xilinx.com:hls:Pool_hls_1:1.0

As shown in the build process:

The only parameter I change within /resetnet50/build.py is the vitis platform to "xilinx_u250_gen3x16_xdma_4_1_202210_1", which is the one I have installed.

Vivado/Vitis 2022.2 and Ubuntu 22.04.4 LTS are being used and the environment variables are set as:

export FINN_XILINX_VERSION=2022.2
export FINN_XILINX_PATH=/tools/Xilinx
export VIVADO_PATH=/tools/Xilinx/Vivado/2022.2
export VITIS_PATH=/tools/Xilinx/Vitis/2022.2
export PLATFORM_REPO_PATHS=/opt/xilinx/platforms
export XILINX_XRT=/opt/xilinx/xrt

Checking vivado.log, the last error call is

# create_bd_cell -type ip -vlnv xilinx.com:hls:Pool_hls_1:1.0 StreamingDataflowPartition_7_Pool_hls_0
ERROR: [BD 5-390] IP definition not found for VLNV: xilinx.com:hls:Pool_hls_1:1.0 
ERROR: [Common 17-39] 'create_bd_cell' failed due to earlier errors.

    while executing
"create_bd_cell -type ip -vlnv xilinx.com:hls:Pool_hls_1:1.0 StreamingDataflowPartition_7_Pool_hls_0"
    (file "make_project.tcl" line 24)
INFO: [Common 17-206] Exiting Vivado at Thu Aug  8 09:06:12 2024...

I thought it would be simple as the bnn-pynq example, which run fine without any modifications but apparently I'm still missing something, I just can't understand what it is.

Another point is the build time: from the first log line to the one that returned a problem it took almost 7 hours, is it normal?

Thanks in advance!

HI @maires1306 , Can you please try using the new release and see if your issue is resolved?

In general, to debug an error message like this, you can have a look into the folders that are generated by FINN. E.g. from the screenshots it looks like the ip generation for one of the Pool layers was unsuccessful. You can have a look at the code_gen_ip_gen_... that belongs to that node and check the vitis_hls.log to get more insights on what could have gone wrong. The folder path gets saved as a node attribute, so you can open the last checkpoint .onnx file with netron, navigate to the problematic node and when you click on it, you should see the ip gen path in the list of node attributes.

@maires1306 Additionally I am curious for the last point you raised about the build time. I am currently working on an older version of FINN also on the resnet50_w1a2, with the first step taking around 30s. Could you maybe link which version of the resnet example you are using exactly and maybe print-debug on which transformation in the tidy up step it hangs for 7 hours?
