Webb29 jan. 2024 · 将批处理 (batch)大小设置为1，这样您就永远不会遇到错误。 如果批处理大小为1，则单个张量不会与（可能）不同长度的其他任何张量堆叠在一起。 但是，这种方法在进行训练时会受到影响，因为神经网络在单批次 (batch)的梯度下降时收敛将非常慢。 另一方面，当批次大小不重要时，这对于 快速测试 ， 数据加载等 很有用。 通过使用 文本 … WebbThe training_data function defines how datasets should be loaded in nodes to make them ready for training. It takes a batch_size argument and returns a DataManager class. For scikit-learn, the DataManager must be instantiated with a dataset and a target argument, both np.ndarrays of the same length.
