When i run the 2D convolution testbench in Pynq-Z1 i found a new problem. Here are the codes.

depth exceeded in comparison
I tried add the sys.setrecursionlimit in py script, but useless.

[tmoreau89]

@lhf1997 on the Pynq set the following env variable

export VTA_HW_PATH=/home/xilinx/incubator-tvm/3rdparty/vta-hw

Then re-run the compilation steps under incubator-tvm/build with

cmake ..
make runtime vta -j2

And re-run the RPC server, and the example. I'll issue a fix to this bug.

[lhf1997]

@tmoreau89 I set the following env variable on the pynq-side and than

cmake ..
make runtime vta -j2

xilinx@pynq:~/tvm/build$ cmake ..

But still have the same bug

File "/home/lhf/tvm/src/runtime/rpc/rpc_endpoint.cc", line 370
RPCError: Error caught from RPC call:
RecursionError: maximum recursion depth exceeded in comparison

Is there a problem with my settings? or just a bug in vta ?

Hi @lhf1997

I had the same issue. Have you tried with Pynq bitstream 0.0.2? It worked for me! But then I got another error. I have opened new issue #7182 on that. See also: https://discuss.tvm.apache.org/t/vta-test-fail-while-running-the-2d-convolution-testbench-on-pynq/8789

Hope this helps.
