我使用tf.data.datsetAPI 并使用残差网络。当我为 TensorBoard 运行代码以可视化我的嵌入时，我遇到了这个错误，但是当我使用两层网络时，我没有这个问题。

def load_and_preprocess_from_path_label(path, label):
    return load_and_preprocess_image(path), label

ds = tf.data.Dataset.from_tensor_slices((all_image_paths, all_image_labels))
with tf.Session() as sess:
    # TODO (@omoindrot): remove the hard-coded 10000
    # Obtain the test labels
    image_label_ds = ds.map(load_and_preprocess_from_path_label)
    ds = image_label_ds.shuffle(image_count)
