python - tensorflow 语音_命令错误: Unsuccessful TensorSliceReader constructor

Question

我正在尝试运行 Speech_Commands Digital Ocean ML Droplet 上的自定义数据示例。我已将单词列表更改为仅包含两个原始单词和一个我自己的单词列表。我还将步骤减少到仅 700。训练后，我使用“--start_checkpoint”和“-output_file”参数运行 freeze.py 文件，但出现以下错误:

知道是什么原因造成的以及如何解决它吗？我假设示例中的代码有效，因为我使用默认值尝试了此操作，然后它就有效了。

Answer 1

所以，事实证明我忘记了更改 freeze.py 文件中所需的单词参数。
