Why does Importerror: Cannot Import NameError Occurs?

Below, are the reason that’s why Importerror: Cannot Import Name occurs in Python:

  • Circular Import
  • Incorrect Module Reference
  • Typo in Import Statement

Circular Import

Below, the code consists of two Python modules, `module_a.py` and `module_b.py`. `module_a` imports `function_b` from `module_b`, and `module_b` imports `function_a` from `module_a`, creating a circular dependency. This circular import structure can lead to the “ImportError: Cannot Import Name” when attempting to use functions from either module.

module_a.py

Python3




# module_a.py
from module_b import function_b
 
def function_a():
    print("Function A")


module_b.py

Python3




# module_b.py
from module_a import function_a
 
def function_b():
    print("Function B")


Output:

Hangup (SIGHUP)
Traceback (most recent call last):
File "Solution.py", line 2, in <module>
from module_b import function_b
Importerror: No module named 'module_b'

Incorrect Module Reference

In below, code `main.py` attempts to import `my_function` from `mymodule`, but `mymodule.py` defines a function named `another_function`. This inconsistency causes an `ImportError: Cannot Import Name` when calling `my_function()` in `main.py`.

main.py

Python3




# main.py
from mymodule import my_function
 
my_function()


mymodule.py

Python3




# mymodule.py
def another_function():
    print("Another Function")


Output:

Hangup (SIGHUP)
Traceback (most recent call last):
File "Solution.py", line 2, in <module>
from mymodule import my_function
Importerror: No module named 'mymodule'

Typo in Import Statement

In `myscript.py`, an attempt to import and execute `my_function` from `utils` causes an `ImportError: Cannot Import Name` because the function is defined later in `utils.py`. To resolve, switch the order of the import statement and function definition in `utils.py`.

myscript.py

Python3




# myscript.py
from utils import my_function
 
my_function()


utils.py

Python3




# utils.py
def my_function():
    print("My Function")


Output:

Hangup (SIGHUP)
Traceback (most recent call last):
File "Solution.py", line 2, in <module>
from utils import my_function
Importerror: No module named 'utils'

Importerror: Cannot Import Name In Python

One common error that developers encounter is the “ImportError: Cannot Import Name.” This error occurs when the Python interpreter is unable to import a particular name or module within your code. In this article, we’ll explore what causes this error and provide solutions to fix it.

What is ImportError: Cannot Import Name?

The “ImportError: Cannot Import Name” error typically occurs when there is a circular import or a dependency loop in your Python code. Circular imports happen when two or more modules depend on each other, creating a loop that confuses the interpreter. As a result, Python raises an ImportError because it cannot determine the correct order of module imports.
