Protein language models scaling laws

The goal of this project is to uncover the best approach to scale large protein language models (ie., learn scaling laws for protein language models) and then publicly release a suite of optimally-trained large protein language models.

Installing enviroment

If you want to run on CPU:

conda env create -f protein_lm.yml
conda activate protein_lm_env
pip install -e .

If you plan to use cuda, use the dedicated .yaml file:

conda env create -f protein_lm_cuda.yml
conda activate protein_lm_env
pip install -e .

Installing tokenizer

This will be integrated to the rest of our installation formula, but for now, you need to run the following to build the Rust dependency of the tokenizer:

pip install -e protein_lm/tokenizer/rust_trie

Training

Toy using local dataset

We recommend using a toy tiny dataset for testing and debugging new changes that do not rely on having a large datset. Such a small dataset is provided in the protein_lm/dataset/uniref folder and an example toy training config yaml that uses this dataset is provided in protein_lm/configs/train/toy_localcsv.yaml. To use this config, at the root project directory (e.g., protein_lm_scaling/), run

python protein_lm/modeling/scripts/train.py --config-file protein_lm/configs/train/toy_localcsv.yaml

This config is actually the default, so the above is equivalent to

python protein_lm/modeling/scripts/train.py

Toy using a HuggingFace dataset

For testing with a HuggingFace dataset, we have an example config yaml in protein_lm/configs/train/toy_hf.yaml. Note that training with this config is a little more involved than the above protein_lm/configs/train/toy_localcsv.yaml:

• When first run, the script will download the processed uniref50 dataset, which could take some time.
• This config will log the loss values and other metrics to Weights and Biases. This will require you to create a wandb account.

You can run with this config by:

python protein_lm/modeling/scripts/train.py --config-file protein_lm/configs/train/toy_hf.yaml

Running on multiple gpus

We can run on a single node with multiple gpus by

torchrun --standalone --nnodes=1 --nproc-per-node <num_gpus> protein_lm/modeling/scripts/train.py --config-file <config_file>

For example, to run on a single node with 3 gpus with the provided protein_lm/configs/train/toy_hf.yaml config file, we can run with

torchrun --standalone --nnodes=1 --nproc-per-node 3 protein_lm/modeling/scripts/train.py --config-file protein_lm/configs/train/toy_hf.yaml

Evaluation

Contact Prediction

The script can be run using APT or ESM. It also has the option of choosing between --method jacobian where contact prediction is computed by categorical jacobian extraction or --method regression logistic regression based contact prediction. See BERT-ESM1b and Rao et al. 2020 for details. Currently, script only supports .a3m files as input.

You can run the contact prediction eval script by

python protein_lm/evalutation/scripts/contact_prediction.py --input /path/to/.a3m --model ESM --tokenizer EsmTokenizer --method jacobian --output /path/to/outputdir

Outputs

• .png file with predicted contacts overlaid on ground truth contact map.
• .csv file with results for each protein.
