Create a new environment with as of now python 3.7 since opencv not available in conda's python 3.8 packages

conda create --name opencv-cuda python=3.7
conda activate opencv-cuda
conda install pytorch torchvision cudatoolkit=10.2 opencv -c pytorch

python

import cv2

If the above is all fine, but in jupyter the "No module named 'cv2'" error still an issue. Make sure to install jupyter in that environment too.

If jupyter is intalled in the base environment but not in opencv-cud it will be started...

You need to point to the directory in which ETAGS file generated and it will be loaded.

git rebase -i -x 'git ci --amend --reset-author -Chead' head~5

ctags -e -R --exclude=.git

This is going to generate a TAGS file in project root

class Example
  def foo
    def foo
      @bar
    end
    bar = (1..10).inject(1, :*)
    puts "bar is #{bar}"
    @wibble = "wibble is #{bar / 30}"
    @bar = bar / 20
  end
end

example = Example.new
example.foo
bar is 3628800
=> 181440
example.foo 
=> 181440

The hard working method, the outer def foo is called only once, on the first invocation, afterward, the nested def foo overrides it and simply returning the @bar variable from the object. The nested def foo still accessing the same object.

Given you are on the development branch and have another branch my_topic
  And want to compare the same file on the two different branches
 When open a file in vim say, Gemfile
 Then type :Gdiff my_topic
  And Vim open Gemfile from my_topic branch in a new split

In your engine's engine.rb file add these line:

module MyEngine
  class MyEngine < Rails::Engine
    config.before_initialize do                                                      
      config.i18n.load_path += Dir["#{config.root}/config/locales/**/*.yml"]
    end
  end
end

I was struggle to set up a nicely formatted git log for a while. What I wanted to achive is to be able to quickly overlook the history including the
branch structure, authors, time of commits, remote and local branches. Here is what I currently use

I used to use this config in the past, there is little problem with this - honestly not too big -, is that all the branches displayed with yellow:

  prlog = log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%ad) %C(bold blue)<%an>%Creset' --abbrev-commit ...
