Hi, I tried some tutorials(deploy\_detection, deploy\_classification, etc) using PYNQ Z1 Board. However, I got the same problem for all the tutorials I ran, on RPC server. ``` File "/home/xilinx/tvm/python/tvm/_ffi/_ctypes/packed_func.py", line 78, in cfun rv = local_pyfunc(*pyargs) File "/home/xilinx/tvm/vta/python/vta/exec/rpc_server.py", line 84, in server_shutdown runtime_dll[0].VTARuntimeShutdown() File "/usr/lib/python3.6/ctypes/ __init__.py", line 361, in __getattr__ func = self. __getitem__ (name) File "/usr/lib/python3.6/ctypes/ __init__.py", line 366, in __getitem__ func = self._FuncPtr((name_or_ordinal, self)) AttributeError: /home/xilinx/tvm/vta/python/vta/../../../build/libvta.so: undefined symbol: VTARuntimeShutdown ``` I searched this Error and found this error was recently solved on [VTA build and execution error with new 3rdparty vta-hw](https://discuss.tvm.ai/t/vta-build-and-execution-error-with-new-3rdparty-vta-hw/6341/10), but still I have the error. My OS’s PYNQ v2.5, and I use the latest commit of TVM(a072da0588c542757d2815832b7f010f530b2428) I would really appreciate if someone let me know why the error happened. Is there anyone who solved this error? ---

Have you confirmed that both TVM installs (on pynq and on your host) are up to date? ---

Yes, both TVM are the same version(a072da0588c542757d2815832b7f010f530b2428), which is updated May 28, 2020. ---

Ok, I’ll try to reproduce the tutorial on the latest TVM. Did you get the bug after updating TVM, or did you install from a fresh git clone? ---

it would be great to add debug statements around the line [https://github.com/apache/incubator-tvm/blob/e561007f0c330e3d14c2bc8a3ef40fb741db9004/vta/python/vta/exec/rpc\_server.py#L84](https://github.com/apache/incubator-tvm/blob/e561007f0c330e3d14c2bc8a3ef40fb741db9004/vta/python/vta/exec/rpc_server.py#L84) to see what symbols are exposed. VTARuntimeShutdown is indeed defined in [https://github.com/apache/incubator-tvm/blob/main/vta/runtime/runtime.h#L74](https://github.com/apache/incubator-tvm/blob/main/vta/runtime/runtime.h#L74) ---

I’ve encountered the same problem with commit ‘da42924a16c5e688bbb31facb3b17ba066b776df’ (2/2 2021) Check the build directory, I found a ‘T’ symbol in CMakeFiles/vta.dir/vta/runtime/runtime.cc.o, but was not appeared within the final libvta.so I tried to rerun the link command in CMakeFiles/vta.dir/link.txt, aka ‘/usr/bin/c++ -fPIC -std=c++14 -faligned-new -O2 -Wall -fPIC -shared -Wl,-soname,libvta.so -o libvta.so CMakeFiles/vta.dir/vta/runtime/device\_api.cc.o CMakeFiles/vta.dir/vta/runtime/runtime.cc.o CMakeFiles/vta.dir/3rdparty/vta-hw/src/pynq/pynq\_driver.cc.o -lcma’ This error disappeared. ---

@cee1 . Thanks for your inputs its worked for me. I am using zcu104 with pynq image 2.6. After the build on the board side , 1. I ran “sudo chmod 777 CMakeFiles/vta.dir/link.txt” otherwise it throws permission denied. 2. Then run “CMakeFiles/vta.dir/link.txt” make sure that in the build directory you the following files : 1. CMakeFiles/vta.dir/vta/runtime/device\_api.cc.o 2. CMakeFiles/vta.dir/vta/runtime/runtime.cc.o 3. CMakeFiles/vta.dir/3rdparty/vta-hw/src/pynq/pynq\_driver.cc.o in my case the last 3rd party directory was missing. if any thing missed in the directory then clean and remove everything from build directory expect " config.cmake" file. then after build is complete rerun the link.txt file. ---

Hello, I am building the latest TVM0.9 on the pynq-z2 development board, and I get an error: VTARuntimeShutdown, I have repeated the build many times, but the same problem occurs. . . . . What do you mean by “run “CMakeFiles/vta.dir/link.txt””, can you elaborate? Looking forward to your reply! ! ! ---

Dear @okkk , Hello, I hope you resolved it. I was not active that’s why i didn’t get back to you. If you have not resolved it simply run the command ‘CMakeFiles/vta.dir/link.txt’ from the build directory. Kind Regards, Harish ---

@cee1 Awesome! It worked for me. I ran test\_benchmark\_gemm.py and test\_benchmark\_topi\_conv2d.py in the tutorial with PYNQ Z1 (v2.6). Thanks 💯
