WebI have been trying to pre-train GP2 models with HF Trainer and Deepspeed, but have noticed large differences between HF trainer's final loss and perplexity vs. that of Deepspeed Zero-3 trainer. For the GPT-2 (100M) model on Wikitext-2-raw dataset on 4 A100 80GB GPU, with the same batchsize=32 per GPU: HF trainer returns: WebIssue #1: Stride Length. GPT-2 was evaluated with a small stride: 32. The reason it gives lower perplexity is because transformer LMs (by default unless you're using something like Transformer-XL) have a finite context size so when you do eval stride length = context length your model is always having to predict some subset of tokens with little to no …
