If you would like to override these defaults, see the Conda docs on managing channels. Starting with minconda module version 4.8.3 we set the default channels (the sources to find packages) to conda-forge and bioconda, which provide a wider array of packages than the default channels do.

Conda will install to and search in these directories for environments and cached packages. On all clusters, we set the CONDA_ENVS_PATH and CONDA_PKGS_DIRS environment variables to conda_envs and conda_pkgs in your project directory where there is more quota available. Note: If you are on Milgram and run out of space in your home directory for Conda, you can either reinstall your environment in your project space (see below) or contact us for help with your home quota. If you are using Conda-installed packages, this should be the only module you load in your jobs. We set some defaults for you in this module, and we keep it relatively up-to-date so you don't have to. This is a read-only environment from which you can create your own. The Miniconda Moduleįor your convenience, we provide a relatively recent version of Miniconda as a module. If you get stuck, you can always ask us for help. When constructing an environment for your work you should load either modules or a conda environment.

Mixing modules and conda-managed software is almost never a good idea. This setup saved me hours of debugging issues, figuring out it’s the wrong package version and then reinstalling everything from scratch.Conda version doesn't match the module loaded I’ve forgotten the environment name 🤦🏼‍♂️Ĭonda env list will list all existing environments. It is much faster than uninstalling all pip packages or all of conda 🍻. It’s possible you will break this one, but you remove it with conda env remove onceoff. No problem, just create a onceoff environment! (hint: conda env create -n onceoff). Same as you would do with pip.īut I often have these once-off notebooks that don’t fit into any project! 🔧 Once you activate the conda environment, you can install any package you want - just type conda install. You have to activate the environment explicitly every time you want to use it in new console session. It’s going to install some basic packages and give instructions for activating created environment. If you have a specific version of python you want to use, run conda env create -n python=3.5 (for version 3.5). Whenever you start working on a new project, just run conda env create -n. System that helps me stay away from the trouble is to create one conda environment per project. If you don’t have it installed, go install anaconda! Use one conda per project to stay away from the trouble! It isolates different python and package versions so they do not interact with each other. (It actually does far more, but we’ll stop here 🤓)Ĭonda can do that because is a package manager, but also an environment manager. It compiles packages before publishing to the package repository so you don’t get compiler errors.It gives you the power to use any python version you want!.conda create -name env-p圓.8 python3.8 numpy1.19.5. It allows you to use different versions of the same package. To create an environment, we use conda create command, followed by the environment name, and a list of packageversion pairs, where versions are optional, with the tradeoff installing the latest versions.it does not know anything about python versions - python 2, python 3? Python 3.5 or 3.6? It can’t help with that.Ĭonda does far more than pip! It’s made for people like you, like me, people doing machine learning and data science.for many packages, it uses your compiler, which could be incompatible - this is where your compiler errors are coming from.it does not support multiple versions of same package installed - that’s why you can’t have to projects using different versions of same package!.The difference is that pip does just that and nothing else! It downloads and installs packages you want to use. Pip (recursive “pip Installs Packages”) is a Python package installer. I can guarantee it does not have to be like that!Īfter you read what pip and conda do and how they work, you won’t be breaking your environment again. Everybody is mix and matching words pip, conda and install until it starts working! And it usually works, until it breaks your environment completely.Īnd you do not know why it broke so you remove and install all packages from scratch. I thought we’re using just python?!”.Īnd I did not know what to answer.

“Is conda just python with preinstalled packages?”. People often ask me “Should I use conda or pip to install packages?”. One of the first things I’ve noticed while coming into Machine Learning Engineer role was package management mess.
