SymbolicRegression Generating Training Datasets Error

When I use the default config to generate training datasets, I encounter this problem ```FileNotFoundError: [Errno 2] No such file or directory: './internbootcamp/libs/symbolic_regression/train_data.pkl'```

Also, there are some mismatches between ```data_config_train_all.jsonl``` and the ```interncamps```:

- First, the data config only contains a part of available bootcamps.
- Second, there are naming errors for ```Cballbootcampes_train.json``` and ```Cballbootcampes_test.json```. The naming format is different from any other config json. The matching names should be ```Cballboot_train.json``` and ```Cballboot_test.json```.
- Some ```data_source``` in the ```data_config_train_all.jsonl``` don't have matching bootcamp classes. I mean the matching bootcamp classes can't be found in the ```internbootcamp```.
