[Fixed] ModuleNotFoundError: No module named ‘numpy’

Summary: The most common cause of ModuleNotFoundError is a faulty installation of the module or importing a module incorrectly. For a successful installation of the module, use pip3 install numpy .

◈ Overview

If you are someone like me who works with lots and lots of data, then Import Error: No module named ‘xyz’ is probably one of the most common errors that you have come across. In this article, I will discuss the causes and solutions to this error in Python.

Example: Suppose that you are trying to import the Numpy library and print an array. However you get an ImportError: ModuleNotFoundError: No module named ‘numpy’ .

➥ Reasons of Import Error: No module Named ‘xyz’

Two major reasons that lead to the occurrence of this error:

  • You have not installed the module correctly, i.e., you are using an older version of the module, which is not compatible with the version of Python you are using.
  • The Python-version/environment where you installed the package is not the same.
    • Note: This usually happens when you have two versions of Python (Python 2.x and Python 3.x simultaneously) installed on your system.

    ◈ Solution

    Let us dive into the probable solutions to our problem.

    ❋ Method 1: Fixing Faulty Installation

    If you are on Python version 3, then you must install the latest version of the package. In our case, we must install the latest version of Numpy . Before we dive into the commands to install the latest version of Numpy , let us look at the following visual, which explains what happens when you try to install an older version of Numpy on Python 3.

    Thus, it is clear from the above example that even though you installed Numpy , the ModuleNotFoundError was not resolved. The reason is you installed an older version of Numpy ,which is incompatible with Python 3.

    • The command to install a particular version of Numpy is:- pip install numpy==x.y.z
      • Here x.y.z re[resents the version of Numpy you want to install, for example:- numpy==1.8.2

      To resolve this issue, you can use the following command in your terminal to ensure that the latest version of Numpy is installed:

      Let’s have a look at the following graphic to visualize the solution.

      ❋ Method 2: Fixing Missing Path

      Sometimes, even the above procedure does not work. Whenever you import a module, python searches the module in specific directories.

      To get hold of all the directories that Python will search, you can use piece of code:

      ModuleNotFoundError: No module named ‘java’

      Error: Solution: You can install java python with following command: After the installation of java python library, error will be solved. Triptych’s answer shows how to use the module to get the info for each stack frame. returns a 4-tuple of the filename, line number, function, and source text of the offending line, so if you want to not display the source text you could just throw that away and concatenate the rest.

      In my Python notebook in Azure Databricks, the following import statement gives the error shown below. It seems I am missing some package.

      How to generate java like stack trace in python?

      In my experience programming with Java, I have become quite fond of the stack traces it generates when my code goes awry, but I feel that the traces generated by python are a bit lacking by comparison. For example, a trace in java might look like this:

      java.lang.RuntimeException at test.package.Example.c(Example.java:20) at test.package.Example.b(Example.java:15) at test.package.Example.a(Example.java:10) 

      Whereas a python trace might look like this:

      Traceback (most recent call last): File "example.py", line **** a() File "example.py", line 2, in a b() File "example.py", line 5, in b c() File "example.py", line 8, in c raise Exception Exception 

      While both of these traces convey basically the same information, I personally find that the trace from java is easier to follow.

      Is there a means to change the format python uses for printing its stack traces, or would that sort of change require me to create a custom exception handler at the root of my program?

      import traceback try: x= 1/0 except Exception as e: print(e) traceback.print_exc() 

      There is a means to change the format Python uses to format its stack traces, and that is that you write your own formatter instead. There is only one built-in format.

      You can assign your own function to sys.excepthook and it will act as a top-level exception handler that will get access to exceptions that were about to rise uncaught and cause the program to exit. There you can make use of the traceback object to format things however you like. Triptych’s answer shows how to use the traceback module to get the info for each stack frame. extract_tb returns a 4-tuple of the filename, line number, function, and source text of the offending line, so if you want to not display the source text you could just throw that away and concatenate the rest. But you’ll have to do the work of constructing whatever output you want to see.

      If you really want to, you can reformat exception tracebacks with the traceback.extract_tb method.

      Is it possible to create python package like in java?

      I have few confusion which m not able to get clear from any source! Like in java we can create a package and add many class file on it which can be called by another class (basically when one create an application which contain too many windows and functions)

      for example: I have created splash_screen.java and main_window.java which can be called and destroyed in index.java

      Is there something like that in Python using Tkinter? If so then how is it possible.

      You can create multiple frame s inside your main Tkinter. Otherwise I would suggest you reading this about merging windows: Tkinter: Merging 2 windows

      Packages are different from GUI. To create a package, make a folder for example — Package1 .Then make an __init__.py file. You don’t need to write anything in this. It can be empty. You just need to name an empty file as __init__.py and then place it in the folder. __init__.py is just used for python to detect that the folder is a package. Then, you can place many more sub-packages or modules in this package.
