How to train a model on whole dataset ?

[mohd-naushaaad]

Hi, can you please tell me what can i do for train a model on whole dataset. as you said on your blog that you used only these symbols ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '-', '+', '=', 'leq', 'neq', 'geq', 'alpha', 'beta', 'lambda', 'lt', 'gt', 'x', 'y'],

My question is that how can i use all 82 symbols for train the model
