如何获得 Jupyter Notebook 以查看其打开环境中的模块？

Question

I am attempting to import cartopy into a notebook but am running into issues. If I do a "conda install cartopy" in my base environment, I get the frozen/flexible solve issue ( https://github.com/conda/conda/issues/9367 ). When I open a new environment and do a "conda install cartopy", it seems like everything works. "conda list" shows version 0.18.0 in that environment. Then I open a Jupyter Notebook from within that environment and try to import it into the notebook but originally got the response "no module named cartopy". I tried fiddling with my environments and settings based on feedback on this page ( In which conda environment is Jupyter executing? ), but now the error is "no module named numpy"! Can someone please help me understand why the notebook isn't seeing these modules? Thank you.

Answer 1

Are you certain that numpy is installed in this new environment?

Given that you are using the Anaconda distribution of Python, you should be able to view/configure your environment and it's installed modules using the Anaconda Navigator. Here you can see a full list of all installed modules, and via the terminal/console, launch a Jupyter Notebook from not only within a specific environment, but within a specific directory!

On the left hand side, you can choose the environment that you want to use to start Jupyter Notebook, and on the right you can view all of the installed modules in that environment. Make sure that jupyter , numpy , and cartopy are all listed as installed packages.

To make sure that I am launching Jupyter from my desired environment, I always launch it directly from the terminal. I "Open Terminal" with my environment, "cd" into the directory that I want to use, and then use the jupyter notebook or jupyter lab command.
