MSC in Canada

Is MS in Canada a better option than in the U.S.? Education is not as good as U.S but if thinking of immigrating permanently then its awesome.

Job opportunities in Canada after MS? Job solely depends on skills and job search strategy . Since Canada is rising in tec job opportunities are increasing too but on the other hand number of international students and job seekers have increased too thus the market is very competitive.

What/how to apply?

How I make virtualenv using Conda and install Django, python there

PLEASE BE NOTED:  My PC has python3.5, pip 9.0.1,conda 4.3.13 installed. 

Step 1: Go the directory where I need the virtual environment to start working.

sifii2013@sifii2013 ~ $ cd drive/Factory/workshop

I want to work in my ‘workshop’.

Step 2: Create a virtual environment there and name it world   .

conda create -n yourenvname python=x.x anaconda

for my case , i need python2.7 and virtualenv name world

sifii2013@sifii2013 ~/drive/Factory/workshop $ conda create  -p world python=2.7

Take note that sifii2013@sifii2013 ~/drive/Factory/workshop $ conda create -n world python=2.7  would create the virtualenv in /user/anaconda3/envs directory- just ‘-n’ instead of ‘-p’

Step 3:  Need to activate virtualenv - “ source activate location_of_env“

sifii2013@sifii2013 ~/drive/Factory/workshop $  source activate /home/sifii2013/drive/Factory/workshop/world

(/home/sifii2013/drive/Factory/workshop/world) sifii2013@sifii2013 ~/drive/Factory/workshop $

Step 4: install Django and check Django version that is installed.

(/home/sifii2013/drive/Factory/workshop/world) sifii2013@sifii2013 ~/drive/Factory/workshop $ pip install Django

(/home/sifii2013/drive/Factory/workshop/world) sifii2013@sifii2013 ~/drive/Factory/workshop $  django-admin.py version

Step 5:   go inside the virtualenv

(/home/sifii2013/drive/Factory/workshop/world) sifii2013@sifii2013 ~/drive/Factory/workshop $ cd world

and start a Django project

(/home/sifii2013/drive/Factory/workshop/world) sifii2013@sifii2013 ~/drive/Factory/workshop/world $ django-admin startproject mysite
