To train my model means fit-tuning or retrain a model?

[wjy979769265]

Sorry, i have question about how to perform fit-tuning in your pre-trained PrettyBig model, because i want to generate some texts related to my dataset.
Thank you very much :)

And i'm tring to train a model follow your guides, I created a json file like this:
And I create a new floder to save my model checkpoint. And i've transfer my dataset to tfrecords file.

{ "n_head": 16, "encoder_path": "encoder", "n_vocab": 50257, "embed_dropout": 0.1, "lr": 0.00025, "warmup_steps": 2000, "weight_decay": 0.01, "beta1": 0.9, "beta2": 0.98, "epsilon": 1e-9, "opt_name": "adam", "train_batch_size": 256, "attn_dropout": 0.1, "train_steps": 100, "eval_steps": 10, "max_steps": 500000, "data_path": "datasets/openwebtext/", "scale": 0.20412414523193154, "res_dropout": 0.1, "predict_batch_size": 8, "eval_batch_size": 8, "iterations": 500, "n_embd": 1024, "input": "openwebtext", "model": "GPT2", "model_path": "mymodel", "n_ctx": 1024, "predict_path": "mymodelprediction.txt", "n_layer": 24 }

And i put my tfrecord data in datasets/openwebtext/,change the dir in inputs.py
files = [os.path.join(params["data_path"], "/movie.tfrecords")]

When I started to train the model,
But i get the error, the optimizer failed failed.

Currently this repo is a bit of a mess and finetuning is not as userfriendly as I'd like it to be. I hope to improve things at some point but currently things are messy and you'll have to tweak a lot of code by hand.

The bug you posted is strange, I've never seen it before. Given what I can read from it, I'd guess it means either the CPU is too slow or you run out of RAM.

Thank you very much!
