[VTA} Error when running autotune tutorial

Troubleshooting
#1

Hello,

I’m trying to run the autotune tutorial for autotuning CNNs to run on VTA.

I get the following error:

Traceback (most recent call last):
  File "autotune.py", line 252, in <module>
    tune_and_evaluate(tuning_option)
  File "autotune.py", line 180, in tune_and_evaluate
    vta.reconfig_runtime(remote)
  File "/home/youn/tvm/vta/python/vta/rpc_client.py", line 32, in reconfig_runtime
    freconfig = remote.get_function("tvm.contrib.vta.reconfig_runtime")
  File "/home/youn/.local/lib/python3.6/site-packages/tvm-0.6.dev0-py3.6-linux-x86_64.egg/tvm/rpc/client.py", line 57, in get_function
    return self._sess.get_function(name)
  File "/home/youn/.local/lib/python3.6/site-packages/tvm-0.6.dev0-py3.6-linux-x86_64.egg/tvm/_ffi/function.py", line 131, in get_function
    "Module has no function '%s'" %  name)
AttributeError: Module has no function 'tvm.contrib.vta.reconfig_runtime'

I’m not really sure what’s wrong. Any help would be appreciated. Thanks!

[AutoTVM] Cannot get remote devices from tracker
#2

have you solved the problem?

#3

In order to run the AutoTuning tutorial on VTA you need to run the device tracker on a host machine, and register the device to the tracker by running tvm/apps/vta_rpc/start_rpc_server_to_tracker.py (you’ll need to modify fleet:9190 with <tracker_host_name>:<tracker_port>

Hi @youn123

Please refer to this two section Start RPC Tracker and Register devices to RPC Tracker

Hope helps,

Does the replies solve your problem? It doesn’t on mine…

python -m tvm.exec.query_rpc_tracker --host=0.0.0.0 --port=9190 –>

key | total | free | pending

pynq | 1 | | | 1 | | | | | 0

Doesnt this mean the RPC tracker is started?

++ I refered to those two sections above which is on tutorial, but it wont work on firstplace.

Does anyone have any advice for this?

I managed to run with the provided scrip: start_rpc_server_to_tracer.py. It should be because of pythonpath setting.

I am getting the same issue. How did you solve it. Your help would be appreciated! I have tried but nothing seem to work.

Thanks.

@rsahu

You can run this script like this.

cd $TVM_HOME
pushd apps/vta_rpc
sudo -E ./start_rpc_server_to_tracker.sh
popd

Note that the script expects to be run the exact folder, that’s why pushd/popd.

Update the ‘flee’ with your host ip/name Also ensure to set the variable for

  • VTA_HW_PATH

I’m getting the same issue as well and I’m pretty sure I’ve tried all the fixes in this thread:

  • The RPC tracker is running and joined correctly
  • PYTHONPATH is set to include tvm/python and tvm/vta/python both on the host and the board
  • Always running the script from the tvm/apps/vta_rpc folder including sudo -E

One difference is that I’m using the ZCU104 board but I don’t see how that affects this.

Any suggestions or just some clarification on how the function registering is supposed to work would be greatly appreciated.
