Language-modeling script "killed" when fine-tuning gpt2-medium
Hello! I’m just getting started with the huggingface libraries for text-generation.I cloned thetransformersrepo from github, and then I was able to successfully run fine-tuning on the GPT-2 small model, on my macbook, using this command…python3 examples/language-modeling/run_language_modeling.py \
    --output_dir=/my/data/gpt2-small-finetune \
    --model_type=gpt2 \
    --model_name_or_path=gpt2 \
    --do_train \
    --train_data_file=/path/to/my_corpus_text.txtFor now, I’m using a very small corpus… with a total of around 150kb of text. The training process took about 30 minutes (which I assume was using the CPU rather than GPU). Once it finished running, I was able to successfully use the fine-tuned model to generate text, like this:python3 examples/text-generation/run_generation.py \
    --model_type=gpt2 \
    --model_name_or_path=/my/data/gpt2-small-finetune \
    --length=100 \
    --prompt="Once upon a time, there was a "Next, I tried running the same exact process, with the same training corpus, but with a new output directory and withmodel_name_or_pathset togpt2-medium…python3 examples/language-modeling/run_language_modeling.py \
    --output_dir=/my/data/gpt2-medium-finetune \
    --model_type=gpt2 \
    --model_name_or_path=gpt2-medium \
    --do_train \
    --train_data_file=/path/to/my_corpus_text.txtThe process starts up and emits some logs, which look normal…09/13/2020 17:31:51 - WARNING - __main__ -   Process rank: -1, device: cpu, n_gpu: 0, distributed training: False, 16-bits training: False

This is a 2019 MacBook Pro with 16 GB of RAM and plenty of free space on the SSD. I’m an experienced Java developer, but I’m a python novice, so I might be missing something critical about the environment.

@lysandremight know this

Killed 9 is very probably a memory error. This wouldn’t be surprising as you’re loading a bigger model in memory. Could you monitor your RAM usage when using the script?

Late reply, but I just ran into this problem and found a solution.You can try to dimish the batch_size.I think that should reduce the memory usage. Keep in mind it will take longer to compute.batch_size = 12 #reduce this number
