use conda environment in sublime text 3

Question

Using Sublime Text 3, how can I build a python file using a conda environment that I\'ve created as in http://conda.pydata.org/docs/using/envs.html

Answer 1

You may use a package called "Conda" from the package repository. Below is a detailed step by step guide for the same (using Windows 10 OS PC, however it should work on other OSs in a similar way):

1. Install Sublime Text 3
2. Press Ctrl + Shift + P to open up the Command Palette
3. Type "package" in the Command Palette search menu.
4. From the options, choose "Install Package Control"
5. Next after install, in the Command Palette type "Package Control: Install Package"
6. Search for "conda" to find "Conda" with the description "Work with conda environments in Sublime Text 3"
7. Navigate to "Preferences -> Package Settings -> Conda -> Settings-Default" to ensure the default settings such as Anaconda installation directory etc. are the same on your system. If they are not, open up "Preferences -> Package Settings -> Conda -> Settings-User", and copy the settings you'd like to update using the format shown in the default settings file as a template.
8. Once installed, a Conda build system will appear in the build sytem menu and conda's commands will be located inside the command palette
9. Choose the Conda build sytem by navigating to "Tools -> Build System -> Conda"
10. Create a test file and save it as test.py with the following code in it:

x = 1
y = 2
print(x + y)

11. Press Ctrl + B to build the file and see the output. If everything is working okay, you should see 3 as the output.
12. If you get an error such as error: [winerror 2] the system cannot find the file specified python, it may mean that Anaconda has different settings on your computer than the default settings. In that case you would need to pass your computer settings to Sublime Text in "Preferences -> Package Settings -> Conda -> Settings-User": 1) Change "executable": "~\\Anaconda3\\python" to the Anaconda python install location on your system, for example "executable": "Z:\\Anaconda3\\python.exe", 2) Change "environment_directory": "~\\Anaconda3\\envs\\" to the default environment directory on your system, for example: "environment_directory": "Z:\\Anaconda3\\envs", 3) Change "configuration": "~\\.condarc" to the path to conda's configuration file on your system for example configuration": "C:\Users\SantaPaws\.condarc"

Note 1: If you do not yet have a .condarc on your system, open "Anaconda Prompt" and type conda config --write-default. This would generate a .condarc file and save it somewhere either on your home directory (C drive) or the Anaconda directory. Search the file using Windows search and find its location. Refer to https://conda.io/docs/user-guide/configuration/use-condarc.html for full instructions.

Note 2: You may need to update the default %PATH% path variable in your system, so that it contains the directories for Anaconda. Type: echo %PATH% both in the "Anaconda Prompt" and the windows cmd prompt to see if these paths are the same, if not, you would need to update it in the windows system environment variable "Path". However, Anaconda recommends caution with doing this, as it can break other things.
