如何解决安装 mxnet 时出现 numpy 错误？

Question

我只是运行默认命令在 windows 上安装 mxnet 但弹出此错误，我需要使用 mxnet 才能运行insightface 库，我想知道我做错了什么

我做了什么：

• 全新安装 python 3.8
• 将我的 python 降级到 3.6.5（不起作用）

Python：3.8.2 CUDA 工具包：10.1

我运行： pip 安装 mxnet-cu101

    - `git clean -Xdf` (cleans all versioned files, doesn't touch

  Add `--force` to your command to use it anyway if you must (unsupported).

请帮忙

Answer 1

我和你有类似的问题。 我的原因是我卸载了 anaconda 但不清楚。 我的 anaconda 环境很乱。 软件包安装在其他地方。 所以我的解决方案是清楚地卸载它然后重新安装它。 有一个 package 来清理 anaconda，你可以谷歌它。

如果手动卸载 anaconda，还需要卸载 python。 也许您还可以创建一个新的 anaconda 环境。 它可能会帮助

Answer 2

似乎它试图构建 numpy package。 解决方法是首先使用 conda 安装它并指定错误消息的版本，此处为 1.16.6：

conda install numpy=1.16.6

然后你可以再次输入：

pip install mxnet-cu101
