I got the following error while importing nnvm on tx2, no matter I installed from pip or compiled from source, any solution ? thanks !
though I can’t import nnvm, but I can import xgboost directly
It also won’t show error if I import xgboost firtst and then nnvm, but it seems I would get another error later when I use tvm.relay.frontend, the error I refer to is segmentation fault when I load gluon.Block using tvm.relay.frontend, but I can use the function to load that block without error on my x86 machine, and I don’t know whether this error actually related to the " nnvm import error "
>>> import nnvm
