In this tutorial, we will explain the step-by-step solution to solve the **attributeerror: module ‘numpy’ has no attribute ‘arrange’**.

Before we proceed to the solutions to solve the error, we will know first: what is NumPy?

## What is NumPy?

The **NumPy (Numerical Python)** is a Python library used for numerical computing.

NumPy provides a **multidimensional array object** along with functions to **manipulate **and perform **mathematical operations** on these arrays efficiently.

It also provides tools for working with arrays of data and integrates well with other libraries for **data analysis** and **scientific computing** in Python.

**NumPy **is widely used in the fields of scientific computing, **data analysis**, and **machine learning**.

## What is an AttributeError?

In a Python program, an **AttributeError** is an exception that occurs if an object doesn’t have the exact attribute that is being called.

It occurs if an attribute reference or assignment fails.

It means that the attribute or method you’re trying to access or call doesn’t exist in the object you are working with.

For example, if you are trying to access an attribute of an object that doesn’t have a defined, or if you misspell the attribute name, you may get an **AttributeError**.

This can also occur when you are trying to call a method which is not defined for a specific object.

Furthermore, you can visit or read the other fixed python errors:

- Attributeerror: ‘str’ object has no attribute ‘items’ [SOLVED]
- Attributeerror: ‘list’ object attribute ‘append’ is read-only
- Attributeerror: module matplotlib has no attribute get_data_path
- Type object ‘datetime.datetime’ has no attribute ‘datetime’

## Why the module ‘numpy’ has no attribute ‘arrange’ error occur?

The module **numpy has no attribute arrange** error occurs when you are trying to use the NumPy function **numpy.arrange()**, yet the NumPy module cannot find the **arrange()** function.

In addition, the error occurs because of the typo error.

For example:

```
import numpy as np
# Create an array using the arange function
my_array = np.arrange(10)
# Print the array
print(my_array)
```

In the example code, this is to assume to create a NumPy array with the numbers 0 through 9 using the **numpy.arange()** function.

However, there is a typo in the function name: **numpy.arrange() **instead of **numpy.arange()**.

If you run the code above, the output will show the following error message:

C:\Users\Dell\PycharmProjects\pythonProject\venv\Scripts\python.exe C:\Users\Dell\PycharmProjects\pythonProject\main.py

Traceback (most recent call last):

File “C:\Users\Dell\PycharmProjects\pythonProject\main.py”, line 4, in

my_array = numpy.arrange(10)

File “C:\Users\Dell\PycharmProjects\pythonProject\venv\lib\site-packages\numpy__init__.py”, line 320, in **getattr**

raise AttributeError(“module {!r} has no attribute “

AttributeError: module ‘numpy’ has no attribute ‘arrange’

## Error may occur due to multiple reasons

- typo error in the function name
- missing import statement
- corrupted installation of the NumPy library

After we analyze the problem, the error will occur, and then in the section below, we will explain the solution to solve the error.

## How to solve the attributeerror: module ‘numpy’ has no attribute ‘arrange’?

Here are the following solutions to solve the **attributeerror: module ‘numpy’ has no attribute ‘arrange’**.

**Solution 1: Check the spelling of the function name**

The solution for this error is very simple. Make sure that you have spelled the function name correctly.

Therefore to resolve this error you have to use the correct spelling which is **np.arange()** and not the **np.arrange()**.

We will use the same example code in the previous example and then the error will be removed.

```
import numpy as np
# Create an array using the arange function
my_array = np.arange(10)
# Print the array
print(my_array)
```

If you run the code it will create a NumPy array with the start numbers 0 through 9 using the **numpy.arange()** function.

Output:

C:\Users\Dell\PycharmProjects\pythonProject\venv\Scripts\python.exe C:\Users\Dell\PycharmProjects\pythonProject\main.py

[0 1 2 3 4 5 6 7 8 9]

**Solution 2: Import the NumPy library**

Before you will used any function from the NumPy library, the first you need to do is import it. You can use this code to import the NumPy library:

`import numpy as np`

The code above will import the NumPy library and it will create an alias **np** for it, which is commonly used in Python code.

**Solution 3: Check the version of NumPy**

You will ensure that you have installed the NumPy library and its version is compatible with the arrange function. You can check the version of NumPy using the following code:

```
import numpy as np
print(np.__version__)
```

If you run the code it will show you the version of your NumPy installed on your system

C:\Users\Dell\PycharmProjects\pythonProject\venv\Scripts\python.exe C:\Users\Dell\PycharmProjects\pythonProject\main.py

1.24.2

If the version of the NumPy is incompatible, you can upgrade it using the following command:

`pip install --upgrade numpy`

**Solution 4: Check the installation of NumPy**

If the above solutions don’t solve the error issue, then there should be a problem with the installation of NumPy. You can uninstall and reinstall the NumPy library using the following commands:

```
#uninstall
pip uninstall numpy
#install
pip install numpy
```

## Conclusion

To conclude, most of the time the Python developer encountered an error, it was due to simple mistakes. You can see in this example that you are getting this **attributeerror: module numpy has no attribute arrange **due to the typo and incorrect import.

For that, it is better that you double-check the method or function you are using before searching for it on the internet.
