Python 3.7.3 : The google-cloud-vision python module - part 002.

I used Windows 8.1 and python 3.7.3 version.
The first step is to install the python module.

C:\Python373\Scripts>pip install --upgrade google-cloud-vision

You can see another tutorial about this python module here.
Let's test the python module.

C:\Python373>python
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD6
4)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from google.cloud import vision
>>> from google.cloud.vision import types
>>> from PIL import Image, ImageDraw

You need to have billing enabled for your Google Cloud Platform project.
Evaluated prices can vary and Google gives us this online calculator, or let us test with a FREE account with 300$.
To change the billing account go to the Google Cloud Platform Console.
Open the console left side menu and select Billing.
If you have more than one billing account then you need to solve this issue, see this webpage.
The Cloud Vision API integrates vision features, like: including image labeling, face, logo, and landmark detection, optical character recognition (OCR), and detection of explicit content, into applications.
You need to set the authentification for your google account and your project, see this page.
The next step is to instantiate a client:

client = vision.ImageAnnotatorClient()

Google provides this tutorial with the same steps as into this tutorial.
You can test and read more about Google Vision on the official page.

The google-cloud-vision python module - part 001.

Google comes with $300 credit for free to sign up into Google Cloud Platform over the next 12 months.
This allows you to deal with access to all Cloud Platform Products.
Today I will show you how to install this platform into your Linux and Windows 10 OS.
For Linux, I used Fedora 26 distro.
Using the Windows 10 operating system and python 2.7 then you can use this command:

pip install --upgrade google-cloud-vision

If you got errors the fix with this command:

C:\Python27\Scripts>pip install --upgrade  --trusted-host  pypi.python.org google-cloud-vision

I run again the command and I don't have errors:

For Fedora 26 distro I used this command to install the python module:

[root@localhost mythcat]# pip install --upgrade google-cloud-vision --ignore-installed
WARNING: Running pip install with root privileges is generally not a good idea. 
Try `pip install --user` instead.
