How to resolve the error ImportError: cannot import name 'GenerationConfig' from 'transformers'

I am using Paperspace for programming. I want to import AutoModelForCausalLMWithValueHead, PPOConfig, PPOTrainer from trl but I I encountered an error. I installed the required libraries such as torch==1.9.0 or 2.0.1, transformers==4.18.0, and trl. After importing the libraries as shown below:

import pandas as pd
import os
import torch
from transformers import GPT2Tokenizer

from trl import AutoModelForCausalLMWithValueHead, PPOConfig, PPOTrainer

I got the error:

ImportError: cannot import name 'GenerationConfig' from 'transformers' (/usr/local/lib/python3.9/dist-packages/transformers/__init__.py)

Please be aware that the code functions correctly when using Google Colab. However, when running it on Paperspace, I encountered an error. It seems that the version of PyTorch on Paperspace is 1.12.1, which is not suitable for my requirements. I attempted to create a virtual environment to install a different version of PyTorch, but unfortunately, the version remains 1.12.1. Although I managed to update PyTorch to higher versions like 2.0.1, I encountered a conflicting dependency error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behavior is the source of the following dependency conflicts.
torchvision 0.13.1+cu116 requires torch==1.12.1, but you have torch 2.0.1 which is incompatible.
torchaudio 0.12.1+cu116 requires torch==1.12.1, but you have torch 2.0.1 which is incompatible.

Even with the latest version of PyTorch, the error persists, and I am still unable to resolve the issue.

Solution

It looks like torchvision and torchaudio are not compatible with your current torch version. Try to install pytorch's stable version (2.0.1) using this command:

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu

or generate the desired combination from https://pytorch.org/get-started/locally/.
