在第一步中，您应该使用真实的值。然后使用predict value替换最后一个值。希望下面的代码可以帮助你。

with tf.Session() as sess:
    saver.restore(sess, './model_saved')
    preds = []
    X_batch = last_n_steps_value
    X_batch = X_batch.reshape(-1, n_steps, 1)
    for i in range(number_you_want_to_predict):
        pred = sess.run(outputs, feed_dict={X: X_batch})
        preds.append(pred.reshape(7)[-1])
        X_batch = X_batch[:, 1:]
        # Using predict value to replace real value
        X_batch = np.append(X_batch, pred[:, -1])
        X_batch = X_batch.reshape(-1, n_steps, 1)
