![]() ![]() The following installation instructions are for the major Python version 3. The simplest way to install OpenCV is to use the package manager for Python called pip. ![]() OpenCV does not come automatically installed with Python. OpenCV is written in C/C++ and has two Python interfaces, CV and CV2. OpenCV stands for Open Source Computer Vision Library, and it provides a common infrastructure for computer vision applications. It may be unclear to see cv, cv2, and OpenCV used interchangeably online. To solve this error, we need to point to the correct path to module.py, which is inside folder_1. Let’s run python script.py from the terminal to see what happens: Traceback (most recent call last): File "script.py", line 1, in ≺module≻ import moduleModuleNotFoundError: No module named 'module' import moduleif _name_ = '_main_': mod.print_re_version() Inside script.py, we will try to import the module we created. In module.py, we will import the re module and define a simple function that prints the re version: import redef print_re_version(): print(re._version_)Ĭlose the module.py, then complete the following commands from your terminal: cd. You can use your preferred file editor, such as Emacs or Atom. Note that we use Vim to create the module.py file in this example. Let’s look at the following steps to perform from your terminal: mkdir example_packagecd example_packagemkdir folder_1cd folder_1vi module.py Let’s look at an example package with a script and a local module to import. You may want to import a local module file, but the module is not in the same directory. Let’s look at the revised code: import reprint(re._version_) 2.2.1 To solve this error, ensure the module name is correct. Let’s try to import the re module with a double e to see what happens: import ree -ModuleNotFoundError Traceback (most recent call last)1 import reeModuleNotFoundError: No module named 'ree' The module’s name is incorrect, in which case you have to check the name of the module you tried to import. There are several causes of the modulenotfounderror: The ModuleNotFoundError occurs when the module you want to use is not present in your Python environment.
