While trying to connect MySQL database with Django 3.2 in my Ubuntu 18.04, I encounted this error. I was not able to pip install mysqlclient in my virtualenv. This short tutorial is about how to fix this issue. If your MySQL setup is running perfect and you are unable to install mysqlclient in virtualenv then first check if there is no installation error outside the environment. If mysqlclient shows no issue then try with the…
To install nodejs in your Ubuntu you have follow the following command. sudo apt install nodejs -y sudo npm i -g n sudo n latest # or sudo n lts if you want to install LTS version. If you get permission issue while executing this command than execute the following command. Using chown command, we are providing proper permission to the logged-in user. Update the folder path if it is different sudo chown -R $USER /usr/local/lib/node_modules/n/bin/n #Or in…
Panda is open source, the BSD-licensed library used for data analysis in Python programming language. It is build on top of two most essential python packages numpy and matplotlib. Numpy provides multidimensional array objects for easy data manipulation which pandas uses to store data. Matplotlib has powerful data visualization capabilities. It is most popularly used for data manipulation and data visualization. Pandas designed to work with tabular form of data which is also called dataframe….
According to matplotlib official, Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. Matplotlib has pyplot as a module that provides a MATLAB-like interface. It is designed to be as applicable as MATLAB, with the ability to use python, and being opensource. There are various plotting techniques in matplotlib pyplot like line plot, histogram, scatter plot, 3D plot, Image plot, Contour plot, Scatter plot, Polar plot, Line plot, 3-D plot and…
Exploratory Data Analysis ( EDA ) is the process of organizing, plotting and summarizing a data set. EDA was developed by one the greatest statistician of all time John W. Tukey. In his book “Exploratory data analysis” in 1977 where the principal for EDA was laid. He said “Exploratory Data Analysis can never be the whole story, but nothing else can serve as the foundation stone.” “Exploratory Data Analysis can never be the whole story,…
In probability theory, two events are said to be mutually exclusive or disjoint events if and only if they can not occur at the same time. For example, while tossing a coin head and tail can not occur at the same time. To understand the independence of events you can check my previous article. In short, Event A and B are independent if and only if P(A ∩ B) = P(A) x P(B). To be independent…
The definition of independence in probability: Event A and B are independent if and only if P(A ∩ B) = P(A) x P(B). Sometimes people misuse the terms independence of events with mutually exclusive or disjoint events or vice versa. Don’t get confused with those two term independence of events is completely different property. To get clear view visit this article. If A and B are independent then P( A | B ) = […
Bayes’s theorem is a way of finding a probability when we have certain other probabilities. Bayes’s theorem is stated mathematically as the following equation: Where A and B are events and P(B) ≠ 0, P(A | B) is also a conditional probability: the likelihood of event A occurring given B is true. P(B | A) is also a conditional probability: the likelihood of event B occurring given A is true. P(A) and P(B) are conditional probabilities…
Suppose two events A and B are mutually inclusive events ( having one or more outcomes in common ). Conditional probability i.e. P( A | B ) is the probability of event A occurring with some relationship to event B. Mathematically, P(A | B) = P(A and B) / P(A) which you can also rewrite as: P(A | B) = P(A∩B) / P(A) where P(A) ≠ 0 Conditional Probability in Real World Suppose the weather forecasts…
In this article, we’ll show you how to install virtual environment in your system and run your python project in virtual environment. A virtual environment is important if you don’t want to disturb what you install for a specific project to others in the same system. You can have multiple virtual environments in one system and each project requirement can be kept in a specific python environment. It is the best practice while working in…
