python - 如何解决导入错误: cannot import name 'Box' from 'bokeh.models' ?

Question

我正在尝试更改坐标引用系 crs到 Bokeh 中的图 block 提供商，建议我使用 geoviews，但安装后我收到此错误

import geoviews as gv

我已经安装了 HoloViews 并重新安装了 Bokeh conda install -c bokeh bokeh conda install -c "bokeh/label/dev" bokeh 但什么也没有

Answer 1

我收到此错误是因为我安装了 jupyter_bokeh 。尝试重新安装常规 Bokeh 并没有解决问题。升级 Bokeh 没有帮助。

HoloViews 似乎依赖于 Panel，需要 bokeh < 2.5.0, >= 2.4.0 。我从 pip 收到的警告阅读:

panel 0.14.4 requires bokeh<2.5.0,>=2.4.0, but you have bokeh 3.1.0 which is incompatible.

因此，降级为 bokeh==2.4.0为我解决了问题。
