Hi Guys,
I run Ch3 KantaiBERT.ipynb instruction, tokenizer.train(files=paths, vocab_size=52_000, min_frequency=2, special_tokens=[ "", "", "", "", "",] ) in step 3: Training a Tokenizer, and get the error "Exception: stream did not contain valid UTF-8". I try to search solution in web, some people got the similar problem as well, but don't solve it. Can anyone tell me how to resolve it?
I skip this trouble cell and run following cells, they can execute normally. So, are correct the outcomes of following cells?
thanks
Book says to open OpenAI_GPT_2.ipynb
but searching at the top of github doesn't find it. Where is it?
In chapter 2, on pg 54, AdamW is imported as the optimizer. But, when we get to the point that we add the optimizer to our code on pg 66, the older BertAdam (not available in v4.x) optimizer is used without being imported. Did you mean to use AdamW there?
transformers v4.x doesn't have the BertAdam anymore and only has AdamW, per https://huggingface.co/transformers/migration.html#optimizers-bertadam-openaiadam-are-now-adamw-schedules-are-standard-pytorch-schedules
