## Uses |
|
|
|
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. --> |
|
|
|
## How to Get Started with the Model |
|
|
|
Download files and use the code below to get started with the model. |
|
|
|
```python |
|
from transformers import AutoTokenizer, T5ForConditionalGeneration |
|
|
|
tokenizer = AutoTokenizer.from_pretrained('sagawa/ReactionT5-product-prediction') |
|
inp = tokenizer('REACTANT:COC(=O)C1=CCCN(C)C1.O.[Al+3].[H-].[Li+].[Na+].[OH-]REAGENT:C1CCOC1', return_tensors='pt') |
|
model = T5ForConditionalGeneration.from_pretrained('sagawa/ReactionT5-product-prediction') |
|
output = model.generate(**inp, min_length=6, max_length=109, num_beams=1, num_return_sequences=1, return_dict_in_generate=True, output_scores=True) |
|
output = tokenizer.decode(output['sequences'][0], skip_special_tokens=True).replace(' ', '').rstrip('.') |
|
output # 'O=S(=O)([O-])[O-].O=S(=O)([O-])[O-].O=S(=O)([O-])[O-].[Cr+3].[Cr+3]' |
|
``` |

## Training Details |
|
|
|
### Training Procedure |
|
|
|
<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. --> |
|
We used Open Reaction Database (ORD) dataset for model training. |
|
Following is the command used for training. For more information, please refer to the paper and GitHub repository. |
|
|
|
```python |
|
python train.py \ |
|
--epochs=100 \ |
|
--batch_size=32 \ |
|
--data_path='../data/all_ord_reaction_uniq_with_attr_v3.csv' \ |
|
--use_reconstructed_data \ |
|
--pretrained_model_name_or_path='sagawa/CompoundT5' |
|
``` |
|
|
