If you're a developer working with Python, you have probably come across the error message "AttributeError module 'numpy' has no attribute array or int" at some point. This error message typically occurs when you're trying to call the `array` or `int` function in NumPy, but the module cannot find them. 

In this blog post, we'll dive into the causes of this error message and provide solutions to help you resolve it quickly. 

## What is NumPy?

Before we dive into the error message, let's take a look at what NumPy is. NumPy is an open-source Python library that is used for mathematical computing, working with arrays and matrices, and linear algebra operations. It's a powerful library that is used in the scientific computing community, machine learning, and data science.

NumPy is built on top of C programming language, which makes it faster than vanilla Python in executing mathematical operations. It has a large collection of mathematical functions and operators, which makes it easier to work with numerical data.

## Causes of the "AttributeError module 'numpy' has no attribute array or int" error message

Now, let's take a look at the causes of the error message. 

1. **Missing NumPy module** 

If you're receiving the error message "AttributeError module 'numpy' has no attribute array or int," it could be that NumPy isn't installed on your computer. You need to install NumPy before you can use it in your code. 

To do this, run the following command in your terminal: 

```python
pip3 install numpy
```

This command would install NumPy on your computer, and you should be able to use it in your Python code. 

2. **Importing NumPy incorrectly**

If you've installed NumPy on your computer, but you're still receiving the same error message, it could be that you're not importing the module correctly. 

To import NumPy, you should use the following code: 

```python
import numpy as np
```

This code imports the NumPy module and gives it the alias `np`, which is the standard naming convention for NumPy. If you're importing NumPy using a different alias, you should change it to `np`.

3. **Missing array or int attribute**

The error message "AttributeError module 'numpy' has no attribute array or int" occurs when NumPy cannot find the `array` or `int` attribute. This could be because you're not calling the function correctly or misspelling it. 

To create an array in NumPy, you should use the following code: 

```python
import numpy as np

arr = np.array([1, 2, 3, 4, 5])
```

This code creates an array of numbers from 1 to 5 using the `array` function in NumPy. If you're still receiving the error message, make sure that you're calling the `array` function correctly and the spelling is correct.

## Solutions to the "AttributeError module 'numpy' has no attribute array or int" error message

Now that we've looked at the causes of the error message, let's dive into the solutions. 

1. **Install NumPy**

If you're receiving the error message because NumPy is missing, you need to install it using the `pip3` command. 

```python
pip3 install numpy
```

This command installs NumPy on your computer, and you should be able to use it in your code. 

2. **Correctly import NumPy** 

If you've installed NumPy on your computer, but you're still receiving the error message, it could be that you're not importing the module correctly. 

To import NumPy correctly, use the following code: 

```python
import numpy as np
```

This code imports the NumPy module and gives it the alias `np`. If you're importing NumPy using a different alias, you should change it to `np`.

3. **Correctly call array or int function**

If you're still receiving the error message after installing NumPy and importing it correctly, it could be that you're not calling the `array` or `int` function correctly. 

To create an array in NumPy, use the following code: 

```python
import numpy as np

arr = np.array([1, 2, 3, 4, 5])
```

This code creates an array of numbers from 1 to 5 using the `array` function in NumPy. If you're still receiving the error message, check that you're calling the `array` function correctly, and the spelling is correct. 

## Conclusion

In conclusion, the error message "AttributeError module 'numpy' has no attribute array or int" typically occurs when NumPy cannot find the `array` or `int` attribute. The causes of this error message are missing NumPy module, importing NumPy incorrectly, or missing the `array` or `int` attribute. 

The solutions to this error message are to install NumPy using the `pip3` command, import NumPy correctly using the standard naming convention, or correctly call the `array` or `int` function. 

By following these solutions, you should be able to resolve the "AttributeError module 'numpy' has no attribute array or int" error message quickly and continue working with NumPy in your Python projects.
