Hello, I’m trying to autotune my CNN to run on PYNQ FPGA using this tutorial.
I get the following error when I run the code:
File "autotune.py", line 256, in <module>
tune_and_evaluate(tuning_option)
File "autotune.py", line 214, in tune_and_evaluate
tune_tasks(tasks, **tuning_opt)
File "autotune.py", line 138, in tune_tasks
autotvm.callback.log_to_file(tmp_log_file)])

measure_batch = create_measure_batch(self.task, measure_option)

raise RuntimeError("Cannot get remote devices from the tracker. "
RuntimeError: Cannot get remote devices from the tracker. Please check the status of tracker by 'python -m tvm.exec.query_rpc_tracker --port [THE PORT YOU USE]' and make sure you have free devices on the queue status.

elif lock.acquire(block, timeout):
I’m pretty sure my FPGA is registered, for when I run
python3 -m tvm.exec.query_rpc_tracker --port 9190
I get
Tracker address localhost:9190
Server List
----------------------------

Queue Status

pynq 1 1 0

Just as a note, on the FPGA side I run
python3 -m vta.exec.rpc_server --tracker=192.168.1.4:9190 --key=pynq
.
while the tutorial says I should run
python3 -m tvm.exec.rpc_server --tracker=192.168.1.4:9190 --key=pynq
The latter gives me this error. You should update the tutorial if it is outdated. Otherwise, any help on figuring out what’s wrong would be appreciated. Thanks!
