运行官方的代码出现Failed to save model graph, error: ''

[wulispa]

VisualDL是2.5.1
paddle是2.4.2

[rainyfly]

是demo的代码吗

[wulispa]

是的

[wulispa]

是demo的代码吗

有生成文件

[rainyfly]

运行graph_test.py成功了应该有一个vdlgraph.xxxxx.log的文件，我刚刚跑了一下我这里没有报错，你那边有没有更详细的错误信息给报出来

[rainyfly]

比如报错的程序堆栈具体在哪一行可以看得到吗

[wulispa]

这个嘛

是跑的这份代码吗

[wulispa]

是的

不清楚原因，等我找一台windows机器复现后回你

[GuoQuanhao]

我也有这个问题，我这样解决了https://github.com/PaddlePaddle/VisualDL/pull/1233，我也是windows

可以了，谢谢哇

[rainyfly]

修复的pr #1244 。 这个修复将在下一个小版本中进入，如果需要在windows下使用，可以参考这个pr中修改的文件在本地对应修改一下。具体可以安装如下操作：
import visualdl
visualdl.path
看一下visualdl的安装路径，然后找到pr中修改的文件对应修改一下即能够生效。
