The Anaconda un-installation can be a dirty process on Windows and Mac, but luckily there are scripts to completely remove all traces of it, and then reinstall it. If you interleave conda and pip commands repeatedly in your Anaconda root or "base" environment, you will be eventually break your Anaconda installation, and must completely remove and re-install Anaconda. USE PIP LAST, after exhausting and using all available conda packages.ĭo not keep interleaving conda and pip installation commands. īOTTOM LINE: Take care using pip inside conda environments! See the following document for more information about using pip inside conda environments. I find that pip corrupts my conda environments less frequently when I do this. After that conda then is informed about the pip package installations. One thing that I usually do is install the conda and pip packages into any new conda environment first (using "conda install -c conda-forge conda pip" at the command line). The best guide to pip and conda together is here: Interoperability is still an "experimental feature". They each build and manage their own package indexes. I prefer the command line, because it is much faster and more precise.īE MINDFUL WHEN USING PIP AND CONDA TOGETHER:īe VERY careful about using pip and conda "side-by-side". You can use "conda" at the command line, OR you use the Navigator Environment and Package Manager GUI. They can manage environments and packages for many other programming languages (e.g., R, JavaScript, for starters) and many others.ĬONDA AT THE COMMAND LINE OR THROUGH THE NAVIGATOR? The conda utility and conda package work in a language-agnostic way. The "pip" command line utility is a package manager for Python-only packages in pip format. ![]() ![]() The "conda" command line utility is an environment manager it is also a full package manager that does everything that the pip utility does. The Python package named "conda" provides a programmatic interface for calling conda functions from within Python programs. It formulates and executes commands via conda, in a similar to how you execute conda commands on the Windows Console or Mac Terminal command line interface. Navigator effectively creates and manages environments (and packages) using the conda utility. Under the covers the Anaconda Navigator "environment manager" executes the commands using the "conda" command line utility. It provides GUI functions for managing environments and packages within conda environments. The "Anaconda Navigator" is the desktop program shipped with the distribution. The "anaconda" (lower case) package is for supporting automated installation of the "Anaconda Distribution" and the "Anaconda Navigator GUI Desktop". When you say "anaconda", you probably mean the "Anaconda Navigator Desktop" graphical user interface, not the python package "anaconda" that gets installed at a terminal command line using conda or pip. There is a body of distinct terminology and semantics in this area. ]ĬLARIFYING TERMINOLOGY about 5 snakes and 1 pip ^) If the package exist in Anaconda Navigator, then this graphical approach will work. Select each green check mark for the desired package in the right-hand column. Individually select each file specified in the requirements.txt file using the Package Manager interface (see image). īUILDING THE ENVIRONMENT GRAPHICALLY USING ANACONDA NAVIGATOR:Ī purely graphical (and manual) alternative is to use the Anaconda Navigator Package Manager GUI. Try this automated script to read and use requirements.txt in conda "on the fly". Then use conda from the command line and specify the environment.yml file in your conda command at the console. See this link for examples of environment.yml file formatting: Make sure the environment.yml file is properly formatted. ![]() To do this, copy the names of all packages from the requirements.txt file into an environment.yml file. ![]() The best way to use a conda and a requirements.txt (the pip package manager installation specification) is to convert the requirements.txt file into an environment.yml file. Then I will go into more detail with more precise terminology for others who have the same questions.ĬONVERT REQUIREMENTS.TXT TO ENVIRONMENT.YML FILE Kate, your question and terminology should be more precise.įirst, I will answer your question.
