When reducing the training set characters, an error is reported: File "/home/jmt/MXfont/mxfont-main/trainer/trainer_utils.py", line 101, in expert_assign r_in, c_in = linear_sum_assignment(prob_in)
ValueError: matrix contains invalid numeric entrie.

There should be a free data matrix, but increasing the batchsize will not cause an error, but I don't want to increase the batchsize. May I ask if there is any solution available

My data is fine, it only uses 556 characters. May I ask what is causing this? I have been locating it for a long time and cannot solve it. Can you provide the following assistance

It seems that the training is unstable. "ValueError: matrix contains invalid numeric entrie." means that the input contains NaN, which can caused by various factors. I cannot know what the reason exactly is, but I guess using less characters than our setting may cause unstable training.

Yes, I used 556 characters for style and 6763 characters for content to train. You guessed it right.
