seaborn clustermap 需要 scipy 可用

Question

我正在尝试在我的笔记本中运行以下单元格，但它无法请求 scipy，即使它已安装并导入到 venv 中

import seaborn as sn
import scipy
sn.clustermap(data)

抛出的错误是

venv\lib\site-packages\seaborn\matrix.py:1250, in clustermap(data, pivot_kws, method, metric, z_score, standard_scale, figsize, cbar_kws, row_cluster, col_cluster, row_linkage, col_linkage, row_colors, col_colors, mask, dendrogram_ratio, colors_ratio, cbar_pos, tree_kws, **kwargs)

RuntimeError: clustermap requires scipy to be available

Answer 1

你可以重新安装 scipy （在你的虚拟环境中）并重新打开你的代码编辑器（我在 VS 中使用 Jupyter），这对我有用。

import seaborn as sns
%matplotlib inline
import scipy

Answer 2

如果您使用 IDE，只需确保 pip install scipy
