Installing the package on Linux using pip

1. PyPI MAIN
   
   

   python3 -m pip install --upgrade zaowr-polsl-kisiel
   



2. TestPyPI
   
   

   python3 -m pip install --index-url https://test.pypi.org/simple/ --upgrade zaowr-polsl-kisiel
   

Removing the package on Linux using pip

python3 -m pip uninstall zaowr-polsl-kisiel

Creating virtual environment and installing the package

[!NOTE]

Complete instructions on managing Python virtual environments

can be found here.

1. Create project directory and open it (directory where you will create your files and where the venv will be created). Below is an example of how to do it through Bash - you can also do it through file explorer
   
   

   testDir=/home/user/test
   

   mkdir -p $testDir
   

   cd $testDir
   

   
   
2. Create venv
   
   

   python -m venv ENV_NAME
   




[!NOTE]

ENV_NAME is the name of your venv, so you can change it however you like



3. Activate the venv (while in the project directory)
   
   

   source ENV_NAME/bin/activate
   

   or

   . ENV_NAME/bin/activate
   



4. Install the package from PyPI
   
   

   python3 -m pip install --upgrade zaowr-polsl-kisiel
   



5. (ADDITIONAL COMMAND) If you want to deactivate the currently active venv
   
   

   deactivate
   



6. (ADDITIONAL COMMAND) To reactivate the venv, navigate to the path where you created the venv and source it again (command shown above in section number 3)

Testing the installation

• Activate the venv (while in the project directory) - Skip this step if you are not using a virtual environment
  
  

  source ENV_NAME/bin/activate
  

  or

  . ENV_NAME/bin/activate
  



• Launch python
  
  

  python3
  



• Import the package
  
  

  from zaowr_polsl_kisiel import load_calibration
  



• Locate the file with calibration params or create new file with structure shown below

• Try reading the params from file
  
  

  # remember to provide appropriate path to the calibration params
  # you can simply create a json file with structure shown above
  calibrationParams = load_calibration("../../tests/calibration_params/calibration_params.json")
  



• Display the MSE value to test if the load succeeded
  
  

  print(calibrationParams["mse"])
