[GitHub] [incubator-tvm] pasqoc opened a new issue #5003: [VTA][Chisel] deploy classification not working when timer() is used

pasqoc opened a new issue #5003: [VTA][Chisel] deploy classification not working when timer() is used
URL: https://github.com/apache/incubator-tvm/issues/5003
 
 
   The deploy_classification.py tutorial does not work when used with Chisel based targets such as TSIM and DE10NANO, suggesting this is a runtime related issue coupled with the Chisel based implementation.
   
   The test runs successfully when replacing the timer() call on line 255 with a direct call to the inference model m.run(), suggesting that the problem maybe due to bad state or re-initialization across subsequent runs commanded by the timer() module which by default makes 12 runs.

   I think this is actually a hardware issue in Chisel implementation of VTA. An incorrect result takes place when we run multiple cycles of inference, due to buffer is contaminated in the first cycle.
