I ran one of my old little programs (that I pasted on the left pane of Spyder) by pressing the play button (the little green triangle) and it worked smoothly on the bottom right pane, while on the top right pane some data appeared coloured indicating if the numbers were part of a list or single integers.ġ) When I launched Spyder from the Anaconda Navigator, a command window pops in and out 6 times, and then it is kept opened, displaying something like ' Active code page: 1252' and if I close that command window, Spyder also closes. Instead, Anaconda provides Spyder, which is fine with me. The author said that Anaconda comes with VS Code.

#ANACONDA INSTALL NEW PYTHON VERSION UPDATE#

I was still using Python 3.7.4 for my little simple programs, but I decided to update and use the latest version of Python installing Anaconda, following the instructions of a book. That is, it will switch your path back to including Anaconda3 instead of Anaconda3/envs/py27.I apologize if this is not the right forum for the following problems and doubts. As long as your path points to Anaconda3/envs/py27 and not Anaconda3, it is as if this is the only version of Python that lives on your computer.ĭeactivating this environment will return you to the root Python 3 environment. You can also use conda (and pip) to install Python 2.7-compatible packages in this environment. Having activated your py27 environment, you can start a vanilla Python console, an iPython console, a Jupyter notebook, run a Python script, etc. Any other terminal session will default to the root conda environment. Note that this path change only occurs effect in that particular terminal session. Thus your system will now find the Python 2.7 executable and its associated libraries in its path. E.g., in Linux you can add the following alias to your ~/.bashrc file:Īctivating an environment simply updates your system’s path, swapping the directory Anaconda3 with Anaconda3/envs/py27 in this instance. Instead, you can create an alias that will allow you manually prepend Anaconda to your path. The simple solution to this is to not have the Anaconda-installer include Anaconda in your path. This can be a big problem if you work in languages other While this makes it very easy for users to install sophisticated Python packages that leverage C-libraries without having to manually build those libraries, it also means that your system will prioritize Anaconda’s files before your system-level files.

At the end of the day you can simply install Anaconda without worrying about any of these details.Īn important note for people who code in languages other than Python: Anaconda has its own lib and bin directories that it uses to store library files and binary files as needed. Those services are written such that they will directly invoke the Python executable that came with the operating system - they will not accidentally run the version of Python that came withĪnaconda. Those operating systems use their native versions of Python to perform some of their services. It is critical that you do not attempt to uninstall, remove, or change this native version of Python.

Thus, by placing theĪnaconda3 directory at the beginning of your path, the Anaconda-installer has ensured that your computer will prioritize Anaconda’s python executable over any other installations of Python on your computer, because it will find that executable first.įor Linux and Mac users, it is very likely that your system already has a version of Python installed. Whenever you execute any command in your computer’s terminal, the computer will quickly search through the directories that are specified in the path for an executable with that name it will execute the first such executable that it finds. Your system’s path is simply a list of directories. If you followed the install instructions as specified above, then the Anaconda-installer also placed this directory in your system’s “path”. The default install location for Anaconda is: It also contains the executable files for all of these applications. This created a directory called Anaconda3 (or some variant of this) on your computer, which contains all of the files associated with the CPython interpreter, all of the modules in Python’s standard library, the aforementioned 3rd party packages that come as part of the Anaconda distribution (e.g. NumPy, SciPy, Jupyter, iPython), and the conda package manager.
