I have tried to add unsqueeze(1) back as same as the old location ( like Chandler Zuo did), but main.py and main_predict.py both cannot running rightly. Could someone tell me how can i solve it? Please

thank you

对比main和main_predict的predict函数，看里面的1和0对着改一下就好了。

Hey I have this same issue, how i can solve this ? I don't understand previous answer :( My error ###################################### Traceback (most recent call last):

Ok I solved this: In main_predict.py in function predict() change the shape from 0 to 1 in y_history t_dat.targs.shape[0] -> t_dat.targs.shape[1]
