Line Profiler - lprun

• Useful to understand the memory and time consumption of each line
  • pip install line_profiler
  • %load_ext line_profiler
  • %lprun?
  • %lprun -f classifier.train classifier.train(X_train, W, Y_train)

Memory Profiles -

• Profiles the memory consumption of a file
  • Step1 - create file

    •  %%file testfunc.py
       def testfunc(X_train, Y_train):
      

  • Step2 - import file and use memory profiler
  • pip install memory_profiler
  • %load_ext memory_profiler
  • from testfunc import testfunc
  • %mprun -f testfunc testfunc(X_train, Y_train)

timeit

• %timeit -n 5 classifier.train(X_train, W, Y_train)

AutoReload

• reload a file in jupyter notebook that you are editing in a .py file
• %load_ext autoreload
• %autoreload 2 #reload all modules
