在 Deepspeech 中抛出“std::length_error”实例后调用终止

Question

我在从头开始训练模型后尝试解码 wav 文件，我完成了训练和测试阶段没有错误，我得到了 WER & CER 和 Loss 值。 注意：我已经用这个命令完成了解码，没有错误，但是当我用新模型测试时出现了。

native_client/deepspeech --model /home/xyz/DeepSpeech/data/exprt_dir/output_graph.pb --scorer /home/xyz/DeepSpeech/data/lm/lm.scorer --audio data/test5.wav --beam_width 9000 > data/decoding.txt

我尝试了不带记分器、管道和梁的命令以及来自火车数据集的文件，但错误仍然存​​在。

你可以在下面找到我拥有的包的版本（运行 pip list 显示的不仅仅是这些包，但我只保留了重要的包）

(deepspeech-venv) (base) root@xyz:/home/xyz/DeepSpeech# pip  list

仅供参考，此问题已在Discourse 上详细讨论。

一般来说，如果您没有积极开发 DeepSpeech，请不要使用 master 分支，因为它有时会中断。
