the error I got:
ValueError: Exception encountered when calling layer “sequential_163” (type Sequential). Input 0 of layer “sequential_161” is incompatible with the layer: expected shape=(None, 10), found shape=(None, 1285, 10, 10) Call arguments received: • inputs=tf.Tensor(shape=(None, 1285, 10), dtype=float32) • training=True • mask=None
How can I solve this problem?
