### Install |
|
|
|
|
|
> In the script below, the `test.jsonl` file in the dataset needs to be renamed to `py500.jsonl`. |
|
|
|
|
|
|
|
|
Install venv |
|
|
|
|
|
`install.py` |
|
|
|
|
|
### Run |
|
|
|
|
|
Run the ground truth oracle |
|
|
|
|
|
`run.py` |
|
|
|
|
|
### Evaluate |
|
|
|
|
|
Evaluate whether an oracle is same with the ground truth |
|
|
|
|
|
`evaluate.py` |
|
|
|
|
|
|
|
