(Obviously change the path to your own project) Set PYTHONPATH=%PYTHONPATH% C:\path\to\project\ Or use built-in PYTHONPATH system variable:Įxport PYTHONPATH="$:/path/to/project/".Try using absolute path in your imports.One way to avoid import errors is to avoid relative paths altogether. Final solution to fixing ModuleNotFoundError No Module Named error: And ImportError for look ups in a from keyword. When the look up fails, Python will throw the ModuleNotFoundError for import keyword. Using the from keyword follows the same pattern. In a large majority of cases these errors occur because Python interpreter fails to resolve the module name in sys.path (the place Python looks in after module look up fails in both sys.modules and the Standard Library. Now that we're somewhat more familiar with how Python imports packages, and we've looked at absolute and relative imports, it's time to take a closer look at ModuleNotFoundError (and ImportError) and see how it can be fixed.

rooster import peck_seeds_function How to fix ModuleNotFoundError and ImportError? Here is another example of a relative import: # importing from the scope of chicken.pyįrom. otherpackage.chicken import lay_egg_function Below are 3 examples of Python's relative imports: # importing from the scope of something.pyįrom. Given example above you can use an absolute import: import package.somethingĪnother example of an absolute import: import otherpackage.chickenĪnd here's an absolute path to the location of the subpackage eggs: import Ī relative import are a lot more common and therefore more prone to import errors. This is where discerning between absolute and relative packages may matter. (Note that packages can include other packages, or "sub-packages".) └── project If you're getting import errors for a more complex reason, consider the structure of package dependencies. This article will explore this error in more depth.

The ModuleNotFoundError: No module named error is raised when Python either cannot find the module you're trying to import, the name of the package being imported was misspelled, or the module doesn't exist on your hard drive.īasically all it means is that you need to install the module/package before it can be imported into your program (with import keyword.)īut of course there is more to it than that. How To Fix ModuleNotFoundError (no module named) Error If previous step fails, Python will try to resolve the module under sys.path which is probably where things went wrong when you received ModuleNotFoundError no module named error.The PSL contains all built-in modules written in C language thatp provide file system access, math library, and various system tools dealing with most common issues. If previous step fails, Python will use Python Standard Library looking.sys.modules is the dictionary map Python will use to lookup module names that have already been loaded (another module could have already loaded it, etc.) and if so, it will become available in the scope from which you're importing it.Next Python interpreter will try to resolve modulename.Add necessary names in local namespace and current program scope.Load and initialize (if required) the module.It will locate the filename associated with imported package.

Let's break down the process to see what Python will do to locate your module: And it takes a bit dissecting to understand.

ImportError: cannot import name 'modulename'īut how does Python know where to look for modules?.

ModuleNotFoundError: No module named 'modulename'.

But if all goes wrong you may receive one of the following two errors: If module can be found ideally this should be enough to start using it. To add a new module use import keyword followed by package name: import modulename A separate tutorial exists for each utils, mysql, jwt, docker, matplotlib, selenium, pandas, pygame, tkinter, cv2, numpy, tensorflow, feras, requests, pip, pil, api. This error is encountered for other popular modules. How to solve ModuleNotFoundError (youtube tutorial) In which case, for visual speed learners, here's a video showing how to fix it: And then try to resolve it with this new knowledge. However, if you work on a more complex project, or your Python isn't configured correctly, you might want to read the rest of this article to understand how Python adds modules to your program. I really hope that the reason you get ModuleNotFoundError no module named error is simply because the module you are trying to include is not installed.
