问题 I would like to use conda to create different environments, each with a different $PYTHONPATH. Currently, I have to change the environment variables each time in my .bashrc. Is there a simple way of creating multiple python environments via conda, such that I can seamless switch (via source activate) and have the corresponding $PYTHONPATHs update automatically? 回答1: You can specify the PYTHONPATH before you execute any script, which would be easier than changing your .bashrc For example, to

问题 I installed Anaconda 3 2.3.0 on Windows xp. It is supposed to be the last version of anaconda to support windows xp as it contains python 3.4.3, and python 3.4.x is the last version of python to support windows xp. When installing a package with conda install ,one of its dependencies was updating conda to conda 4.x. conda 4.x crashed in the commandline when running conda install . This made anaconda unusable that i uninstalled anaconda. My question, is it possible to lock versions of packages

问题 Scenario I'm trying to setup a simple docker image ( I'm quite new to docker, so please correct my possible misconceptions ) based on the public continuumio/anaconda3 container.

问题 How does running source activate <env-name> update the $PATH variable? I've been looking in the CONDA-INSTALLATION/bin/activate script and do not understand how conda updates my $PATH variable to include the bin directory for the recently activated environment. No where can I find the code that conda uses to prepend my $PATH variable. 回答1: Disclaimer: I am not a conda developer, and I'm not a Bash expert. The following explanation is based on me tracing through the code, and I hope I got it

问题 I have Python 2.7 as root. I need to install the package "statistics" in Python 3.6, and it is not in the environments of anaconda navigator. How can install "statistics" with conda or pip for a secondary Python environment? 回答1: Create a new Python 3 environment by running: conda create --name python3 python=3 If you want all the standard anaconda packages installed by default, do: conda create --name python3 python=3 anaconda Whenever you need to use python3 run: activate python3 Then use

问题 I've just updated my MacBook to Catalina. After the update, zsh can't find anymore. In fact, in my .zshrc I had: export PATH=/anaconda3/bin:$PATH However, the path /anaconda3/bin doesn't exist anymore. Does that mean that I have lost all of my environment? 回答1: You can find the entire anaconda3 environment in a shortcut link named 'Relocated Items' on your desktop. It appears as though the upgrade to Catalina does not allow the Conda environment to be installed under a user directory now

问题 I previously had Conda running smoothly on Mojave, but I've found that the upgrade to Catalina moves the "anaconda3" folder to your Desktop > Relocated Items > Security > anaconda3. It seems Catalina's security settings may not allow applications to install directly under the user directory anymore. I tried the suggestion here, written below: Hi, I might have a solution Copy the folder anaconda3 located in Relocated Items to /Users/myname/ Open Terminal Enter: export PATH=''/Users/myname
