This article provides an in-depth analysis of common shape incompatibility errors when building LSTM models in TensorFlow/Keras, particularly in multi-class classification tasks using the categorical_crossentropy loss function. It begins by explaining that LSTM layers expect input shapes of (batch_size, timesteps, input_dim) and identifies issues with the original code's input_shape parameter. The article then details the importance of one-hot encoding target variables for multi-class classification, as failure to do so leads to mismatches between output layer and target shapes. Through comparisons of erroneous and corrected implementations, it offers complete solutions including proper LSTM input shape configuration, using the to_categorical function for label processing, and understanding the History object returned by model training. Finally, it discusses other common error scenarios and debugging techniques, providing practical guidance for deep learning practitioners.
