【问题描述】：

我无法在我的 Windows 机器上安装 tsne 包。我按照指令here 为 Python 安装了 tsne 包。但是pip install tsne 或pip install git+https://github.com/danielfrg/tsne.git 都可以。错误消息是

我正在为 python 使用 Anaconda，我也为 Windows 安装了 Visual C++ 编译器。

【问题讨论】：

您的头文件似乎丢失了。包含路径中是否包含 clbash.h 的库？
你能解决这个问题吗？

标签： python pip

【解决方案1】：

很抱歉，如果您已经尝试过此操作，但我看不到您在命令提示符中键入的内容以获取该错误。

如果你没有将你的路径变量设置为 pip，那么输入它（如果 python 在不同的目录中，只需更改路径）并记住它的大小写敏感！

C:\Python34\Scripts\pip install LIBRARY_NAME

【讨论】：

我已经设置了 pip 路径变量。通常“pip install”会起作用，但是这次当我输入“pip install tsne”时，我收到了这个错误消息

【解决方案2】：

尝试从 sklearn 导入 TSNE。
在开始导入库时编写以下代码：

from sklearn.manifold import TSNE

【讨论】：

【解决方案3】：

试试这个conda install -c conda-forge tsne。来自 Anaconda 的参考link
