Numpy is the best python package for the creation of NumPy array and using it you can make mathematical calculations very easily. Sometimes you get errors while installing NumPy like no module named numpy or np error e.t.c. There can be a case when a particular third party package requires a specific version of the NumPy. In this entire tutorial, you will know how to downgrade your NumPy packages easily through steps.
Why you should downgrade Numpy?
Now the question comes about why you will downgrade Numpy. And there can be many reasons. But the most obvious reason for downgrading the NumPy package is the use of other external python packages. Sometimes there is a package that requires some specific version of the numpy to work than the latest one.
Therefore you have to install numpy for the specific version. So that the third-party package works.
Steps to Downgrade Numpy
In this section, you will know all the steps required to downgrade the NumPy version. Just follow the steps to downgrade it quickly.
Step 1: Open your terminal
The first step is to open your terminal of command prompt.
Step 2: Check the version of the Numpy
The second step is to check the version of the NumPy. You can check the version of the Numpy in your system by using the numpy.__version__.
Type python on your terminal. It will open the python interface. After that type the below lines of code one by one.
>>import numpy >>numpy__version__
You will get the python version
Step 3: Downgrade and Install Numpy
Now suppose I want to install NumPy of version 1.18.1 then you will write the numpy==1.18.1. It will be done using the pip command. But before that, you have to also check the version of the python in your system.
To check the version of the python you have to use the following command.
You will use the pip3 command if the version of the python is 3. xx and use pip if the version of python is 2. xx.
In my system the version of the python is 3. xx so I will use the pip3 command.
pip3 install --upgrade numpy==1.18.1
The above command will downgrade the version of NumPy if the current version of the numpy in your system is above. In addition, it will install the specified version of the Numpy which is 1.18.1.
Downgrading Numpy requires when there is a functionality in the third-party package that doesn’t support the current version of the Numpy. If you are getting errors the above steps to downgrade Numpy will fix your issue.
