How to set Tensorflow 2 on Colab.research.google.com
This simple tutorial show you how to set Tensorflow 2 version in google Colab. It is simple step by step, picture by picture guide.
I try to find a way to set Tensorflow 2 version on Colab. Are you using Colab? I love it.
Set a version of Tensorflow
To set the Tensorflow version in colab.research.google.com- execute following code %tensorflow_version
- go to top menu - Runtime - Restart and Run all
[0]:%tensorflow_version 2.x
 |
| Point 1 set Tensorflow version |
 |
| point 2 restart runtime |
Test the Tensorflow 2 version
After set version and restart of runtime try to use Tensorflow 2.0 and print version. If you have version of Tensorflow 1.x somethink weht wrong. Add new code section as follows
In [0]:
from __future__ import absolute_import, division, print_function, unicode_literals
try:
# %tensorflow_version only exists in Colab.
%tensorflow_version 2.x
except Exception:
pass
import tensorflow as tf
import matplotlib.pyplot as plt
import numpy as np
print(tf.__version__)
# This looks like a vector right ?
tensor_OneDimension = np.array([1,2,3,4,5])
# The acess tensor elenents by index
first_element = tensor_OneDimension[0]
last_element = tensor_OneDimension[4]
print("first element :",first_element)
print("second element:",last_element)
print("--------------------------------")
# This tensor looks like an Matrix.
tensor_TwoDimensionMatrix = np.array([[1, 2],[3, 4]])
# Access matrix elements by index
print(tensor_TwoDimensionMatrix)
print("--------------------------------")
print(tensor_TwoDimensionMatrix[0][0])
print(tensor_TwoDimensionMatrix[1][0])
print(tensor_TwoDimensionMatrix[0][1])
print(tensor_TwoDimensionMatrix[1][1])
print("--------------------------------")
# print all elements of first Row and second Row
print("Print 1 row by [:][0]",tensor_TwoDimensionMatrix[:][0])
print("Print 2 row by [:][1]",tensor_TwoDimensionMatrix[:][0])
print("--------------------------------")
# print columen by
print("Print 1 row by [0][:]",tensor_TwoDimensionMatrix[:][0])
print("Print 2 row by [1][:]",tensor_TwoDimensionMatrix[:][0])
print("--------------------------------")
Expected result of print(tf.__version__)

| print Tensorflow version 2.1.0 |
