【问题描述】：
我正在尝试安装包含尽可能多的依赖项的 NeuralProphet 包。 我在 Python 3.8.5 上运行它可能是 python 版本问题？ 这是我的错误：
$ pip install neuralprophet

ERROR: Cannot install neuralprophet==0.2.5, neuralprophet==0.2.6 and neuralprophet==0.2.7 because these package versions have conflicting dependencies.
The conflict is caused by:
neuralprophet 0.2.7 depends on torch<1.7.0 and >=1.4.0
neuralprophet 0.2.6 depends on torch<1.7.0 and >=1.4.0
neuralprophet 0.2.5 depends on torch<1.7.0 and >=1.4.0
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

此外，我已经从 Github 下载了存储库，并从包文档中执行了安装步骤，如下所示：http://neuralprophet.com/ 我在编写 pip install 命令时遇到这些错误：

我遇到了类似的问题：我按照 pytorch 安装说明安装了 CUDA 11.1 和 torch 1.8.0。我正在使用 python 3.7.3 并安装了 NVIDIA Nsight 2020.3.1.21012。我有一个 NVIDIA RTX 2080（移动）GPU。尝试 pip install neuralprophet 时收到以下错误消息：错误：找不到满足要求的版本 torch=1.4.0（来自 neuralprophet[live]）（来自版本：0.1.2、0.1 .2.post1, 0.1.2.post2, 1.7.0, 1.7.1, 1.8.0, 1.8.1) 错误：找不到匹配的分布 fortorch=1.4.0 (来自neuralprophet [live ])

文档中没有提到不支持torch >= 1.7.0。但这似乎是错误消息所说的内容？火炬必须 >= 1.4.0 且 =11。

你好，卡尔。我发现我的 Python 版本是 32 位的，而 pytorch 似乎需要 64 位的版本。对我来说，它奏效了。所以让我知道它是否对你有用。

我将我的 pytorch 降级到 1.6.9（我认为），这是介于 > 1.4.0 和
