冲突的原因是： 用​​户请求的tensorboard==2.1.0 tensorflow 1.15.4依赖于tensorboard<1.16.0 and >=1.15.0

Question

我正在尝试从 git 存储库安装 VIBE 包，并且最初我正在安装它的依赖项。代码位于此处： https: //github.com/mkocabas/VIBE我应该如何解决这个问题？

这是我得到的错误：

Answer 1

这里的关键是：

The conflict is caused by:
    The user requested tensorboard==2.1.0
    tensorflow 1.15.4 depends on tensorboard<1.16.0 and >=1.15.0

这是因为https://github.com/mkocabas/VIBErequirements.txt中存在冲突，因为它需要和。但是，根据错误消息，该版本仅适用于.tensorboard==2.1.0tensorflow==1.15.4tensorflowtensorboard 1.15.0 - 1.15.x

如果您仔细阅读该错误，您会发现它pip本身建议如何解决此问题：

要解决此问题，您可以尝试：

1. 放宽您指定的软件包版本范围
2. 删除软件包版本以允许 pip 尝试解决依赖冲突
