检查失败:mdb_status == 0(2与0)没有这样的文件或目录

问题描述

我在训练数据时收到以下错误.我已经尝试了Internet上提供的所有解决方案，但似乎没有任何工作对我有用.我检查了路径，并且lmdb文件的大小不为零.但是问题仍然存在.我不知道如何解决这个问题.

I received the following error while I was training the data. I have tried all the solutions given on the internet and nothing seems to work for me. I have checked paths and size of the lmdb files are non-zero. But the problem still exists. I have no idea how to solve this issue.

推荐答案

您尚未正确设置LMDB目录的路径.转到创建LMDB的目录，并使用以下命令获取绝对路径:

You have not set your paths to the LMDB directories correctly. Go to the directory where you have created your LMDBs and get the absolute paths using this command:

$ readlink -f <LMDB_directory_name>

使用此路径，应该可以解决您的问题.

Use this path, it should solve your problem.
