MAX_EXPR_LENGTH did not take effect

[wangtianqi1993]

When running train_AFF.py, it was found that the MAX_EXPR_LENGTH parameter in alphagen.config.py did not take effect, meaning there is currently no parameter to control the length of the generated expressions.

Yes,thank you for your feedback, this is a bug caused by code iteration.

You could set MAX_EXPR_LENGTH through modifying following code in train_aff.py:

for seed in seeds:
    reseed_everything(seed)
    class cfg:
        name = f'{save_name}_{instruments}_{train_end}_{seed}'
        # 
        max_len = 20   《----------------------  Modify Here to control max length

        batch_size = 256
        potential_size = 100
        n_layers = 2
