Anaconda

问题 I was suggested to conda create a new environment for installing tensorflow First question, in general: Why do environment exist in conda or in Python ? (Why) is it preferable to install a new library in a new environment ? Here, in practice: After install conda shell says $conda activate test will activate the test environment. Does it mean i can't access the lib in Spyder unless i activate test in conda shell ? Do i need to restart python shell to see the lib ? I can't access the lib ( no

问题 I need to activate environment in docker and run a command in this environment. I create the environment, but then I try to activate this environment and run the command in this way: CMD [ "source activate mro_env && ipython kernel install --user --name=mro_env" ] but when I ran docker I get an error: [FATAL tini (8)] exec source activate mro_env && ipython kernel install --user --name=mro_env failed: No such file or directory This is the whole Dockerfile: FROM continuumio/miniconda3 ADD /src

问题 Whenever I try to perform any operation that requires connecting to any conda channels, e.g. update --all , I get the following error, always in the first step: OpenSSL.SSL.Error: [('SSL routines', 'ssl3_read_n', 'unexpected eof while reading')] The workaround is uninstalling and then installing the entire Anaconda distribution. After that any conda command works as expected for the rest of the day. BUT the next day I start getting the above error again. I know it's not due to any networking

问题 I'm using MAC OS and installed python2, then miniconda python2, and then Anaconda python3. Now normally in terminal my python version would be python3, but if I activate a conda environment "test", then the default python will be python2. I believe the reason is the $PATH is changed, at "base" env (when terminal started), the starting part is "/anaconda3/bin:/anaconda3/condabin" , and after "conda activate env" , it changed to "/anaconda3/envs/test/bin:/anaconda3/condabin" which do not have

问题 I cannot update packages in anaconda navigator. Procedure: 1. Update index 2. mark packages, that I want to update 3. click apply After a while the window remains empty and nothing happens (see figure). I already deleted anaconda completely from my computer and installed it again. The problem remains. I tried to update packages from the command line: conda update --all and it seem to work. But when I checked my anaconda navigator for updatable packages, it shows me 194 updatable packages in

问题 I can run python files in cmd promt and Vscode terminal (cmd prompt). When I try to run any programme with Code runner ( "code-runner.runInTerminal": false ), I get the following error: [Running] python "c:\Users\MY PATH INCLUDING WHITESPACE\hello_world.py" Python was not found but can be installed from the Microsoft Store: https://go.microsoft.com/fwlink?linkID=2082640 Here are the user settings (settings.json) I have tried: "code-runner.executorMap": { "python": "python", }, "code-runner

问题 I followed the instructions on installing RISE for Jupyter notebook with Anaconda (conda) but the "Enter/Exit RISE Slideshow" button never showed in the toolbar. I followed the recommendations on solving the problem in the two closed RISE issues (#137, #275), but with no luck. I updated Jupyter to the latest version, started a new notebook, hard refreshed the browser page, reinstalled Rise and still no button. I also saw this SO question, which is different from my case since I never saw the
