请问你的代码是基于paython2还是paython3de

what's the difference between train.py and main.py?It seems to be the same expect for a little bit differences.

I have noticed that in your crnn+attention's code, you define the forward function of crnn class by three variables:input length text, while I can not find the length text as the error msg shows:
TypeError: forward() missing 2 required positional arguments: 'length' and 'text'

and your code shows below

def forward(self, input, length, text):
# conv features
conv = self.cnn(input)
b, c, h, w = conv.size()
assert h == 1, "the height of conv must be 1"
conv = conv.squeeze(2)
conv = conv.permute(2, 0, 1) # [w, b, c]

        # rnn features
    crnnShare,_ = self.rnnShare(conv)
    T, b, h = crnnShare.size()
    t_rec = crnnShare.view(T * b, h)
    CTCEmbed = self.embeddingCTC(t_rec)  # [T * b, nOut]
    outputCTC = CTCEmbed.view(T, b, -1)
    AttentionEmbed = self.embeddingAttention(t_rec)  # [T * b, nOut]
    AttentionInput = AttentionEmbed.view(T, b, -1)
    outputAttention = self.attention(AttentionInput, length, text)
