Summary: pip vs CondaĪnother fundamental difference between pip and Conda is less about the tools themselves, and more about the package repositories they rely on and how they work.

They’re not wheel-specific, they’re available to any package in the Conda environment.Ĭonda can do this because it’s not a packaging system only for Python code it can just as easily package shared libraries or executables. Those installed libjpeg and libpng can then be depended on by other installed packages. The following NEW packages will be INSTALLED:

#Pip vs pip3 zip file

In order to deal with shared library dependencies like libpng, any shared library external dependencies get bundled inside the wheel itself.įor example, let’s look at a Pillow wheel for Linux a wheel is just a ZIP file so we can use standard ZIP tools: The way pip solves this problem is with packages called “wheels” that can include compiled code.

On Linux or macOS you can install the system packages or the Homebrew packages for Windows this can be more difficult.īut you’re going to have to write different configuration for every single OS and even Linux distribution.

In order to compile Pillow yourself, you have to install all of them, plus their development headers. The Pillow image graphics library, for example, relies on third party shared libraries like libpng and libjpeg. This can be quite slow, wastes resources, is often painful to configure, and still doesn’t solve a big part of the problem: shared library dependencies. The original solution was to have each user compile the code themselves at install time. In the early days of Python packaging, a package included just the source code that needed to be installed.įor pure Python packages, this worked fine, and still does.īut what happens when you need to compile some Rust or C or C++ or Fortran code as part of building the package? Solution #1: Compile it yourself Beyond pure Python: Packaging compiled extensions That’s a big enough topic that it gets a whole new section, next.

  • Consistent configuration: You don’t need to install system packages and Python packages in two different ways (almost) everything can go in one file, the environment.yml.īut it also addresses another problem: how to deal with Python libraries that require compiled code.
  • Reproducibility: It’s possible to pin almost the whole stack, from the Python interpreter upwards.
  • Portability across operating systems: Instead of installing Python in three different ways on Linux, macOS, and Windows, you can use the same environment.yml on all three.
  • In part it’s about portability and reproducibility. Why did Conda make the decision to package everything, Python interpreter included? Need to ship quickly, and don’t have time to figure out every detail on your own? Read the concise, action-oriented Python on Docker Production Handbook. Note: Outside any specific best practice being demonstrated, the Dockerfiles in this article are not examples of best practices, since the added complexity would obscure the main point of the article. This base image ships with Conda pre-installed, but we’re not relying on any existing Python install, we’re installing a new one in the new environment.

    Here’s what the pip requirements.txt would look like:įROM continuumio/miniconda3 COPY environment.yml.

  • Conda packages include Python libraries (NumPy or matplotlib), C libraries ( libjpeg), and executables (like C compilers, and even the Python interpreter itself).įor example, let’s say you want to install Python 3.9 with NumPy, Pandas, and the gnuplot rendering tool, a tool that is unrelated to Python.
  • Pip packages are Python libraries like NumPy or matplotlib.
  • The fundamental difference between pip and Conda packaging is what they put in packages. The starting point: which kind of dependencies?

  • Focusing on the Conda-Forge package repository Conda has multiple package repositories, or “channels”.īy the end you should understand why Conda exists, when you might want to use it, and the tradeoffs between choosing each one.
  • Linux, including running on Docker, though with some mention of macOS and Windows.
  • Python only Conda has support for other languages but I won’t go into that.
  • While it’s not possible to answer this question for every situation, in this article you will learn the basic differences, constrained to:
  • What are the tradeoffs between the two?.
  • If you’re using Python in the world of data science or scientific computing, you will soon discover that Python has two different packaging systems: pip and Conda.
