如何修复“类型错误：列表索引必须是整数或切片，而不是元组”

Question

     12         for ii, (x, y) in enumerate(get_batches(train_x, train_y, batch_size), 1):
     13             feed = {inputs_: x,
---> 14                     labels_: y[:, None],
     15                     keep_prob: 0.5,
     16                     initial_state: state}

TypeError: list indices must be integers or slices, not tuple

Answer 1

As the error message states, y is a list. So you cannot have two values in the brackets. That is how numpy arrays work. You should probably change your code to the following:

feed = {inputs_: x,
        labels_: np.array(y)[:, None],
        keep_prob: 0.5,
        initial_state: state}

Answer 2

thanks but this method did not solve the problem. I found the solution when the problem is done as follows.

        y = np.array(y)
        feed = {inputs_: x,
                labels_: y[:, None],
                keep_prob: 0.5,
                initial_state: state}
