Question

我有一个带有Autoencoder的docker容器，可以通过Flask-Server启动。所有脚本都被复制到Docker的/ root中，它还可以访问共享卷/数据，如下所示：

/数据
- /图像
- /型号
- / Autoenc.exe.ckpt.data-00000-的-00001
- / Autoenc.exe.ckpt.index
- / Autoenc.exe.ckpt.meta
- /检查点

和
/根
-MyServer.py

服务器可以成功将图像写入/ data / images文件夹，但无法写入/ data / models目录。我像这样实例化了tensorflow Saver：

saver = tf.train.Saver()

并尝试了以下每种编写保存文件的方法

saver.save(sess, '/data/models/Autoenc.exe.ckpt')
saver.save(sess, '../data/models/Autoenc.exe.ckpt')

有趣的事实：当我这样做时，它可以正常运行

saver.save(sess, './Autoenc.exe.ckpt')

但这会将文件写入错误的位置，在重建docker容器时将删除该位置。构建docker容器并且已经在提到的目录中提供检查点时，通过

进行恢复

saver.restore(sess, "../data/models/Autoenc.exe.ckpt")

没有任何问题..

不要让我告诉你错误信息：

如果需要更多信息，请随时提出进一步的问题。感谢您的帮助，因为我开始失去理智。

Answer 1

我认为，它可以对目录'/ data / models /'进行权限。请检查运行 saver 进程的容器用户。

要测试，docker exec -it bash并尝试在目录'/ data / models /'中创建一个文件。

Tensorflow Saver.save无法写入docker共享卷
