ImportError: cannot import name 'amp' from 'torch.cuda'

Description When running from simpletransformers.classification import MultiLabelClassificationModel I am met with ImportError: cannot import name 'amp' from 'torch.cuda'

Details Running on Anaconda Jupyter Notebook. My imported modules:

import pandas as pd
import numpy as np
import sklearn
from sklearn.model_selection import *
import transformers
import simpletransformers
import torch
import apex

Importing modules are all good. Installed apex using conda install -c conda-forge nvidia-apex and pytorch using conda install pytorch torchvision cpuonly -c pytorch

Tried to troubleshoot with solutions in this thread: https://github.com/NVIDIA/apex/issues/621 but nothing has worked so far,

Full Error
