问题 I'm working with a Jupyter Notebook written in Python 3, and I would like to run Python 2 scripts from within that Notebook. I was wondering if it's possible to run Shell commands from within the Notebook, and have these Shell commands running under a different environment. For example, if env2 is a Conda environment that runs Python 2, and env3 runs Python 3, and my Jupyter Notebook runs in env3, maybe I could write within my Notebook: ! source activate env2 ! script_that_uses_python2.py and

Is there any way to get pandas working with the jupyter notebook from SageMath on Windows? thanks a lot for every answer 回答1: After

问题 Sorry if this is a stupid question. I use python/jupyter a lot and it's stopped working after updating from Mac OS High Sierra to Big Sur.

When I try python3 , pip -v , conda , etc. it says "command not found". python still seems to run, but it's 2.7 and I know I had 3 (I probably had a few versions from untidy file systems). I want to avoid reinstalling all my packages and things again, because I know it's

问题 I have Jupyter QtConsole installed in Ubuntu 16.04. How can I set default configuration like font family, size and initial imports? 回答1: The docs on configuration options for jupyter will be very helpful here. In short, open ~/.jupyter/jupyter_qtconsole_config.py in your favorite text editor and find your options of interest. Font family : c.ConsoleWidget.font_family Font size : c.ConsoleWidget.font_size Startup scripts and initial imports will be a little more complicated since those are
