iniself / noba Goto Github PK

rt，谢谢指导！

Throw an exception “'WindowsPath' object is not subscriptable” when “from noba import core”

in windows python 3.9

When running the sample:

from backtrader_bokeh import bt as bt_bokeh
plot = bt_bokeh.Bokeh()
cerebro.plot(plot, iplot=False)

there is nothing displayed in the Jupyter Lab cell output except: " BokehJS 2.4.3 successfully loaded."

Versions of packages:

• backtrader-bokeh==0.8.9
• bokeh==2.4.3
• jupyter-bokeh==3.0.7
• jupyter-lab: 3.4.8

Is there something else I may be missing?

是不是依赖的matplotlib版本太低了，不支持python10。

Hello! I got the following error in notebook. I tried both VS Code and Jupyter Notebook - same error.

Appreciate any solution!
