I was trying to quantize model which is having dense layers in the main script the dense layers are turned off, But if I uncomment the
´@register_annotate_function(“nn.dense”)´
which gives rise to tvm._ffi.base.TVMError: Traceback (most recent call last): [bt] (8) /home/.local/lib/python3.6/site-packages/tvm-0.7.dev1-py3.6-linux-x86_64.egg/tvm/libtvm.so(tvm::relay::MixedModeMutator::VisitExpr(tvm::RelayExpr const&)+0x5c3) [0x7f75968f7dc3]
