Measuring uTVM inference time

Hi everyone. I am trying to measure the inference time for my ML model with STM32 board using uTVM. I am following the tutorial microTVM with TFLite Models — tvm 0.8.dev0 documentation.

I am trying to use time_evaluator to measure the inference time(like for other targets when using TVM) but it seems like there is some issue with the function when using it with uTVM. ftimer = graph_mod.module.time_evaluator("run", session.context,number=1, repeat=1) prof_res = np.array(ftimer().results) * 1000 # multiply 1000 for converting to millisecond print("%.2f ms" % np.mean(prof_res))

   Traceback (most recent call last)
<ipython-input-28-7ce7584c44b6> in <module>
      1 ftimer = graph_mod.module.time_evaluator("run", session.context,number=1, repeat=1)
----> 2 prof_res = np.array(ftimer().results) * 1000  # multiply 1000 for converting to millisecond
      3 print("%.2f ms" % np.mean(prof_res))

What is the correct way of doing this? Also is there a way to know the memory requirements of the model for the MCU.

Thanks

hi @aakah18151, can you try using the debug runtime? see create_local_debug_runtime

Thanks @areusch This works. :slight_smile:

@areusch I am trying to run a different tflite model from the tutorial given by @tgall_foo . I am getting error while running.

How to fix this. In general is there anything special that need to be done to run some other model using uTVM apart from the standard sine_model.

@aakah18151 we don’t quite have good enough debugging for this right now for me to be certain, but based on your stack trace and that it’s inside

[bt] (6) /tvm_micro_with_debugger/tvm/build/libtvm.so(tvm::runtime::RPCClientSession::AllocDataSpace(DLContext, unsigned long, unsigned long, DLDataType)+0x2b7) [0x7f7abd9b11b7]

I would suppose that your runtime doesn’t define enough memory for that model (or fragmentation issues with the JSON parsing are making the model require much more memory than it should). we are working to address these with AOT runtime and memory planner improvements. in the meantime, see if you can increase the amount of global memory made available in main.c or switch to the Zephyr heap allocator as demonstrated here.

Thanks @areusch . Unfortunately increasing the memory size did not work. The other thing I tried is to replace my /tvm/tests/micro/qemu/zephyr-runtime/src/main.c with the “main.c” from blog-post eval which did not work either. Is there a working microTVM code apart from sine model on the same board which I can refer to?

What am I missing here?

@aakah18151 tests/micro/qemu/test_zephyr.py should work on STM32f746xx board. that should test sine_model.tflite. You can run it with:

python tests/micro/qemu/test_zephyr.py --microtvm-platforms=stm32f746xx

is this the tutorial you’re trying?

@areusch
I tried to reduce the model size, however I am getting this error

This seems to be some different error from earlier.

Hey @areusch It seems like I am unable to set the lowed model parameters in to graph_mod, which is why I am getting this error. I am able to run this sine_model microTVM with TFLite Models — tvm 0.8.dev0 documentation using similar steps but when passing the lowered parameters from my model I am getting this error.

@aakah18151 sorry for the delay. hm, it seems to me like you might be somehow allocating too much memory for your device in the runtime. you could be overwriting the stack when you set_input. unfortunately we don’t have a good way to detect this at the moment, though Zephyr should provide you a summary of memory used. When Zephyr does this, it assumes a certain maximum stack depth. do you have an idea how close you are to the actual stack depth? perhaps you could try reducing the amount of memory by ~10kB and see if you get a different error (remote device terminated connection means it’s likely that the device rebooted, which would likely happen if the stack was overwritten). the different error may not exactly be a human-readable string (we don’t currently have a good way to report numeric error codes from include/tvm/runtime/crt/error_codes.h), but it would lend confidence to the idea that this is what’s happening.

Thanks @areusch . I finally got this working. However, right now I am giving the parameter using set_input(**params) to the runtime. I tried using --link params while building, but then I get RPC session timeout error @ mod.run()

Interesting. Could you capture your terminal output with logging.basicConfig(level=logging.DEBUG)? Perhaps I can diagnose how far it’s getting.

@areusch Here is the captured debug output. I had to divide it in three parts due to word limitation.

hi @aakah18151,

I tried the following thing:

  1. Start at rev 072c469c0 (origin/main).
  2. Uncomment the relevant code in tutorials/micro/micro_tflite.py and change to use debug runtime:

I have a bunch of things in flight and forgot there is a bug in the debug runtime. I didn’t see exactly your error message–I saw this instead:

I was able to fix the bug with this patch. Could you try it?

Thanks!
