I've tried and failed to reproduce this on a fresh Ubuntu machine. Still fails consistently on the original machine, but it's possible something interesting happened to the installation there. Will come back if I figure something out. Backtrace, omitting a bunch of python at the bottom. ``` #0 __GI___pthread_mutex_lock (mutex=0x20) at ../nptl/pthread_mutex_lock.c:65 #1 0x00007fffd808407a in mxnet::engine::ThreadedEngine::WaitForVar(mxnet::engine::Var*) () from /home/ubuntu/mxnet-operator/python/mxnet/../../build/libmxnet.so #2 0x00007fffd826b751 in mxnet::NDArray::SyncCopyToCPU(void*, unsigned long) const () from /home/ubuntu/mxnet-operator/python/mxnet/../../build/libmxnet.so #3 0x00007fffd7f5744b in MXNDArraySyncCopyToCPU () from /home/ubuntu/mxnet-operator/python/mxnet/../../build/libmxnet.so #4 0x00007ffff5749dae in ffi_call_unix64 () from /usr/lib/x86_64-linux-gnu/libffi.so.6 #5 0x00007ffff574971f in ffi_call () from /usr/lib/x86_64-linux-gnu/libffi.so.6 #6 0x00007ffff595d5c4 in _ctypes_callproc () from /usr/lib/python3.6/lib-dynload/_ctypes.cpython-36m-x86_64-linux-gnu.so #7 0x00007ffff595dc33 in ??
