Interestingly this PR seems to have introduced a bug in the VTA image classification example: https://github.com/apache/incubator-tvm/commits/master/vta/tutorials/frontend/deploy_classification.py To reproduce you can go back to `d892881c4cc8c9a29bc03233aeac2b1532a9c6891` and the test passes. Edit the config.cmake lines to run the VTA simulator: ``` echo 'set(USE_VTA_FSIM ON)' >> config.cmake echo 'set(USE_LLVM llvm-config-10)' >> config.cmake ``` Go to `3684a51728e929576c93ff9887ac23e1b51582de` (this PR), and the test fails with the following stack trace: ``` Stack trace: [bt] (0) 1 libmxnet.so 0x000000011a0e92b0 mxnet::Storage::Get() + 4880 [bt] (1) 2 libsystem_platform.dylib 0x00007fff690495fd _sigtramp + 29 [bt] (2) 3 libvta_fsim.dylib 0x0000000136ad14d0 _ZZN4dmlc16ThreadLocalStoreIN3tvm7runtime16VTAWorkspacePoolEE3GetEvE4inst$tlv$init + 0 [bt] (3) 4 ??? 0x0000000137dd1494 0x0 + 5232202900 [bt] (4) 5 libtvm.dylib 0x0000000131d09f3c tvm::relay::Interpreter::InvokePrimitiveOp(tvm::relay::Function const&, tvm::runtime::Array<tvm::runtime::ObjectRef, void> const&) + 3516 [bt] (5) 6 libtvm.dylib 0x0000000131d0824b tvm::relay::Interpreter::Invoke(tvm::relay::InterpreterClosure const&, tvm::runtime::Array<tvm::runtime::ObjectRef, void> const&, tvm::relay::Var const&) + 171 [bt] (6) 7 libtvm.dylib 0x0000000131d03481 tvm::relay::Interpreter::VisitExpr_(tvm::relay::CallNode const*) + 961 [bt] (7) 8 libtvm.dylib 0x0000000131d070f8 tvm::relay::ExprFunctor<tvm::runtime::ObjectRef (tvm::RelayExpr const&)>::InitVTable()::'lambda4'(tvm::runtime::ObjectRef const&, tvm::relay::ExprFunctor<tvm::runtime::ObjectRef (tvm::RelayExpr const&)>*)::__invoke(tvm::runtime::ObjectRef const&, tvm::relay::ExprFunctor<tvm::runtime::ObjectRef (tvm::RelayExpr const&)>*) + 24 [bt] (8) 9 libtvm.dylib 0x0000000131d05aaf tvm::NodeFunctor<tvm::runtime::ObjectRef (tvm::runtime::ObjectRef const&, tvm::relay::ExprFunctor<tvm::runtime::ObjectRef (tvm::RelayExpr const&)>*)>::operator()(tvm::runtime::ObjectRef const&, tvm::relay::ExprFunctor<tvm::runtime::ObjectRef (tvm::RelayExpr const&)>*) const + 255 Stack trace: [bt] (0) 1 libmxnet.so 0x000000011a0e92b0 mxnet::Storage::Get() + 4880 [bt] (1) 2 libsystem_platform.dylib 0x00007fff690495fd _sigtramp + 29 [bt] (2) 3 ??? 0x0000000000000012 0x0 + 18 [bt] (3) 4 libtvm.dylib 0x0000000131e652ee void* std::__1::__thread_proxy<std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, tvm::runtime::threading::ThreadGroup::Impl::Impl(int, std::__1::function<void (int)>, bool)::'lambda'()> >(void*) + 62 [bt] (4) 5 libsystem_pthread.dylib 0x00007fff69055109 _pthread_start + 148 [bt] (5) 6 libsystem_pthread.dylib 0x00007fff69050b8b thread_start + 15 Stack trace: [bt] (0) 1 libmxnet.so 0x000000011a0e92b0 mxnet::Storage::Get() + 4880 [bt] (1) 2 libsystem_platform.dylib 0x00007fff690495fd _sigtramp + 29 [bt] (2) 3 ??? 0x0000000000000012 0x0 + 18 [bt] (3) 4 libtvm.dylib 0x0000000131e652ee void* std::__1::__thread_proxy<std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, tvm::runtime::threading::ThreadGroup::Impl::Impl(int, std::__1::function<void (int)>, bool)::'lambda'()> >(void*) + 62 [bt] (4) 5 libsystem_pthread.dylib 0x00007fff69055109 _pthread_start + 148 [bt] (5) 6 libsystem_pthread.dylib 0x00007fff69050b8b thread_start + 15 Stack trace: [bt] (0) 1 libmxnet.so 0x000000011a0e92b0 mxnet::Storage::Get() + 4880 [bt] (1) 2 libsystem_platform.dylib 0x00007fff690495fd _sigtramp + 29 [bt] (2) 3 ??? 0x0000000000000012 0x0 + 18 [bt] (3) 4 libtvm.dylib 0x0000000131e652ee void* std::__1::__thread_proxy<std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, tvm::runtime::threading::ThreadGroup::Impl::Impl(int, std::__1::function<void (int)>, bool)::'lambda'()> >(void*) + 62 [bt] (4) 5 libsystem_pthread.dylib 0x00007fff69055109 _pthread_start + 148 [bt] (5) 6 libsystem_pthread.dylib 0x00007fff69050b8b thread_start + 15 ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
