AttributeError: module 'omegaconf._utils' has no attribute 'is_primitive_type'. Did you mean: 'is_primitive_dict'?

I want to try using BioGPT and I followed the instructions to install the required tools (Moses、fastBPE、sacremoses、sklearn) Then I run the following code

import torch
from fairseq.models.transformer_lm import TransformerLanguageModel
m = TransformerLanguageModel.from_pretrained(
        "checkpoints/Pre-trained-BioGPT", 
        "checkpoint.pt", 
        "data",
        tokenizer='moses', 
        bpe='fastbpe', 
        bpe_codes="data/bpecodes",
        min_len=100,
        max_len_b=1024)
m.cuda()
src_tokens = m.encode("COVID-19 is")
generate = m.generate([src_tokens], beam=5)[0]
output = m.decode(generate[0]["tokens"])
print(output)

but i get the following error

    old_primitive = _utils.is_primitive_type
AttributeError: module 'omegaconf._utils' has no attribute 'is_primitive_type'. Did you mean: 'is_primitive_dict'?

Where should my pre-trained BioGPT model code be placed?

I am also getting error with omegaconf. Did you find solution?

For anyone who is facing this issue, try to replace is_primitive_type with is_primitive_type_annotation
