Error on testing test_multibit_multitile in bismo/src/main/resources/cpp/app/BISMOTests.hpp

See original GitHub issue


First thank you for your effort on developing bismo accelerator and all runtime lib. I face some test failure on bismo testing.

The following is my situation (I use PYNQ Z1 board with v2.4 pynq image):

[1bit config output error] When I config bismo to run alexnet 96, 363, 3025, 256, 2400, 729, 384, 2304, 169, 384, 3456, 169, 256, 3456, 169, 4096, 9216, 1, 4096, 4096, 1, 1000, 4096, 1

// Following is my code

  cout << "AlexNet START" << endl;
  all_OK &= test("layer1", 96, 363, 3025, 1, 1);
  all_OK &= test("layer2", 256, 2400, 729, 1, 1);
  all_OK &= test("layer3", 384, 2304, 169, 1, 1);
  all_OK &= test("layer4", 384, 3456, 169, 1, 1);
  all_OK &= test("layer5", 256, 3456, 169, 1, 1);
  all_OK &= test("layer6", 4096, 9216, 1, 1, 1);
  all_OK &= test("layer7", 4096, 4096, 1, 1, 1);
  all_OK &= test("layer8", 1000, 4096, 1, 1, 1);
  cout << "AlexNet END" << endl;

layers 384, 2304, 169, 384, 3456, 169, 256, 3456, 169 all cannot pass test And when pynq runned to 4096, 9216, 1 Pynq stalls and simply disconnected to host

[8bit Config output Error] Again when I config bismo to run alexnet 8b It says it is RHS is too big and cannot be supported by current runtime

Exception: RHS is too large and not currently supported in runtime library.

Could you help fix this issue? I think runtime lib should able to handle configuration from a commonly used network architecture for completeness.

Many Thanks, Yun-Chen

I am using LD_LIBRARY_PATH=$(pwd) ./testapp i , which is interactive mode for benchmarking. Thank you for such professional and detailed answer! I did look into those files before. I will definitely look into those files more closely again and maybe double check my understanding with you later.

Please feel free to close this issue!

Sincerely, Yun-Chen

Those errors are because fpga-tidbits is missing, it is a submodule – it looks like you need to make a new clone of that branch with the --recurse-submodules flag with something this:

git clone --recurse-submodules --branch dynamic_fetch

or go into the existing cloned folder and run git submodule init; git submodule update
