pip3 does not deploy customized DPU

[haipnh]

Hi,

After successfully building a single core DPU for ZCU104, I manually copied DPU-PYNQ directory to my board I ran this command:

pip3 install /home/xilinx/DPU-PYNQ --no-build-isolation

I opened a notebook, created a overlay object to load the dpu.bit, and investigate its properties by overlay? command. It showed:

Type:            DpuOverlay
String form:     <pynq_dpu.dpu.DpuOverlay object at 0xffff659435b0>
File:            /usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq_dpu/dpu.py
Docstring:      
Default documentation for overlay /usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq_dpu/dpu.bit. The following
attributes are available on this overlay:

IP Blocks
----------
axi_vip_2            : pynq.overlay.DefaultIP
DPUCZDX8G_1          : pynq.overlay.DefaultIP
DPUCZDX8G_2          : pynq.overlay.DefaultIP
axi_vip_1            : pynq.overlay.DefaultIP
ps_e_0               : pynq.overlay.DefaultIP

So I went to the Jupyter terminal and manually copied the required files:

cd /home/xilinx/DPU-PYNQ/boards/ZCU104
cp dpu.bit dpu.hwh ../vitis_platform/dpu/dpu.tcl binary_container_1/dpu.xclbin /usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq_dpu

I restarted the resnet50 again, ran overlay? command again and it showed:

Type:            DpuOverlay
String form:     <pynq_dpu.dpu.DpuOverlay object at 0xffff659434f0>
File:            /usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq_dpu/dpu.py
Docstring:

ps_e_0               : pynq.overlay.DefaultIP

My question is how can we support to looking for the local bitstream files before getting online prebuilt ones?

Thank you in advance.

Hi there,

That's just the order of priority of the dpu.py module. You could try to pass it an absolute path to where your custom bitstream resides and that should work without having to copy files over. That is a good point, in future releases we could consider swapping the priority order to look for a local bitstream first...

Thanks Shawn

Hi @skalade ,

Thank you for replying.

I mean looking for local bitstream first when use pip3 command, not when use dpu.py module.

I close this issue and look forward to next releases.
