Not able to quantize network

I am trying to quantize a model, but when I give model to TVM gives errors

TVMError: Check failed: it != type_definitions.end(): There is no definition of tensor_int32_t

also, it gives following error without passing relay.quantize.qconfig

TVMError: Check failed: it != type_definitions.end(): There is no definition of List

I also meet this problem when I quantize DeepLabV3+ model.
