@Sagnik_Mukherjee thank you for your response.
Actually, I was looking for a more technical response. Searching for libraries to tokenise the dataset, build vocabulary etc I found torchtext package which, is implemented by Pytorch but because it is a different package, it has a different version (at the time of writing 0.8.0a0+c4a91f2) from Pytorch.
Is this package is one of the recommended ways to prepare data for the model or are there others that are more preferable?
p.s. since I will use GloVe embeddings your tip about nn.Embedding.from_pretrained was helpful.
Regards.
