Python Top Libraries You Need to Create ML Model

Creating a Model of Machine Learning in Python, you need two libraries. One is 'NUMPY' and the other one is 'PANDA'.


For this project, we are using Python Libraries to Create a Model.
What Are Key Libraries You Need I have explained in the below steps. You need Two.
NUMPY - It has the capabilities of CalculationsPANDA - It has the capabilities of Data processing. To Build a model of Machine learning you need the right kind of data. So, to use data for your project, the Data should be refined. Else, it will not give accurate results. Data AnalysisData Pre-processing How to Import Libraries in Pythonimportnumpy as np # linear algebra
importpandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)

How to Check NUMPY/Pandas installed After '.' you need to give double underscore on both the sides of version. 
How Many Types of Data You Need You need two types of data. One is data to build a model and the other one is data you need to test the model. Data to build…

Top tips to execute Commands in R Language

The next step after installing R is how to run commands. You can run directly by entering commands. The other way is you need to write an R script, that contains all the series of commands. The benefit of the script is you can save your commands, it saves your time. Second, as a script, you can run it whenever you need.

Executing Commands in R

Commands can be entered directly into the R console (the window that opens when you start R),
following the red > prompt, and sent to the computer by pressing enter.

For example, typing 1 + 2 and pressing enter will output the result 3:
> 1+2
[1] 3
Your entered code always follows the > prompt, and output always follows a number in square
brackets.
  • Each command should take its own line of code, or else a line of code should be continued with { } 
  • It is possible to press enter before the line of code is completed, and often R will recognize this. For example, if you were to type 1 + but then press enter before typing 2, R knows that 1+ by itself doesn’t make any sense, so prompts for you to continue the line with a + sign. At this point, you could continue the line by pressing 2 then enter. This commonly occurs if you forget to close parentheses or brackets. 
  • If you keep pressing enter and keep seeing a + sign rather than the regular > prompt that allows you to type new code, and if you can’t figure out why, often the easiest option is to simply press ESC, which will get you back to the normal > prompt and allow you to enter a new line of code. 
Capitalization and punctuation need to be exact in R, but spacing doesn’t matter. If you get errors when entering the code, you may want to check for these common mistakes:
  1. Did you start your line of code with a fresh prompt (>)? If not, press ESC.
  2. Are your capitalization and punctuation correct?
  3. Are all your parentheses and brackets closed? For every forward (, {, or [, make sure there is a corresponding backward), }, or ]

R Script

Rather than typing a command in a console, you can create a script using a group of commands.  Code (commands) can be typed here, and then entered into the console in one of three ways:
  1. Copy the code in the R script and paste in the console
  2. Right-click on a line or highlighted group of lines and choose “Run line or selection”
  3. Place your cursor on a line or highlight a group of lines and press CTRL+R. 
The Scripts in R-Language are powerful and re-usable.
