无法在 Jupyter Notebook 上安装 fastai

Question

我目前正在尝试使用命令conda install -c fastai fastai 在 conda 环境中安装 fastai，如安装 guide 所示。这是运行该命令时出现的内容：

(fastai) C:\>conda install -v -c fastai fastai

我不能说我完全理解这里的问题所在。我以前认为这是 PyTorch 的问题，但在成功安装 PyTorch 后，我仍然收到此消息。关于如何在我的环境中安装此软件包的任何想法？任何帮助表示赞赏。谢谢！

尝试从 python3.8 降级到 python 3.7，它对我有用。
