运行报错！求助

[LittleMaWen]

您好，我正在复现您的实验，unbuntu16.04，python3.7，我首先运行了train.py文件，出现了以下错误，请问该如何解决？诚盼回复

[Walleclipse]

根据issue 7, 需要把 train.py 中的 121行改成以下形式:
y = np.random.uniform(size=(x.shape[0], 512))

[LittleMaWen]

谢谢谢谢您！解决了！现在正在运行！感谢！另外我在刚刚关闭的问题里问过您了，就是首先python train.py之后，接下来的步骤是怎样？train.py是在训练模型嘛？我在实验报告里也没有找到详细的运行步骤，烦请回复，谢谢您！

[Walleclipse]

train.py 就是训练模型。之后你可以用 test_model.py进行模型的测试。
本项目训练出的模型是一个speaker embedding 模型，也就是输入一段语音，输出一个512维的embedding表示，此表示可以用于说话者验证或者识别等不同领域。
接下来我不太清楚你要达到的目的是什么？
有关训练流程和画出误差曲线你可以查看 issue 1
有关训练后如何进行 inference 你可以查看 issue 30
有关声纹识别你可以查看 issue 21

[LittleMaWen]

嗷嗷~谢谢您！我昨天早晨修正错误后就开始运行了，今早发现运行过程中出现了错误，具体如下：
OSError: [Errno 30] Read-only file system

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

请问您知道是什么原因么？

[Walleclipse]

我不太清楚。你报错的代码块是写入log的那一段，可能是你的操作系统没有写的权限？
你可以查看 pypa/virtualenv#209 或者 https://askubuntu.com/questions/1082876/oserror-errno-30-read-only-file-system 或者 https://forums.fast.ai/t/how-can-i-load-a-pretrained-model-on-kaggle-using-fastai/13941/4

[LittleMaWen]

OKOK谢谢您！非常感谢您不厌其烦为我解答谢谢您！

[LittleMaWen]

嗯嗯~学长，这个问题已经解决了，是我自己系统的问题。
现在我已经python train.py两天多了，程序还在运行，

这是最近一条显示结果，我看到您在其他问题中回答train.py是个无限循环的，需要自己kill掉，请问我现在这个结果是可以kill掉了吗？我不是很明白

[LittleMaWen]

学长，我在训练到下面这个结果时kill掉了这个程序，
2019-08-20 12:24:52,587 [INFO] train.py/main | == Presenting step #211143

然后按照学长说的test_model.py了一下，得到了这个结果，
Found checkpoint [checkpoints/model_211000_0.00100.h5]. Resume from here...
Found 0000368 files with 00003 different speakers.
f-measure = 0.9999999999995, true positive rate = 1.0, accuracy = 0.99999999999998, equal error rate = 0.0
学长，请问是这样吗？

[Walleclipse]

应该是对的。但你这个是在完整的LibriSpeech数据上跑的还是我这个repo里面的LibriSpeechSamples上跑的？
你需要用完整的数据集。

[LittleMaWen]

是的学长，谢谢您回复，我现在才打算用完整的数据集重新跑一遍。我下载了train-clean-100和train-clean-360，我看实验报告，如果我没有理解错的话，请问是否应该先pre_process.py 得到train-clean-100-npy，然后再train.py?
另外就是实验报告中提到的test-clean数据集，请问这是作为测试集的吗？它在哪一部分使用？在跑LibriSpeechSamples时，我也只看到用了train-clean-100中的一部分音频，没有找到test-clean的部分。

[Walleclipse]

1. 是先通过 pre_process.py 来预处理数据，随后再train
2. test_clean 数据集也是从 Librispeech 这里下载的，test_clean是专门用来测试的数据

[LittleMaWen]

学长，抱歉打扰，之前的问题已解决。我用完整的数据集train-clean-100进行了python train.py，好像训练得太久了，得到的losses.txt文件结果：

这时候我就kill掉了train.py，然后python test_model.py得到了结果：
f-measure = 0.5833333333328472, true positive rate = 0.5, accuracy = 0.9857142857142851, equal error rate = 0.08017492711370261
请问学长，我是不是训练得太久了？然后这个结果是这样吗？另外请问demo里面的两张图EER.png和loss.png是怎么得到的？我python utils.py好像什么都没得到？

[MAGUADIDI]

你好，我也想复现这个实验，可以指导一下吗？

[izhangy]

你好，在pre_training.py运行时出现：Found 0000368 files with 00003 different speakers.，一直不动了，请问是怎么回事？

[MAGUADIDI]

没有遇到这个问题。从字面理解，你的人数太少了，而且样本也有些少。
