I am using Raspbian Stretch with desktop and recommended software new version which is released in 2018-11-13. I am using raspberry pi 2 modal B.

I tried to install tensorflow according to recommended google guide. LINK

How to solve this error?

Update:

When I run sudo pip3 install tensorflow --upgrade --no-cache-dir, it say following detail but I can not import tensor library to my project.

It seems that it is caused by some packages' version conflict problems. The virtual environment solution at Install TensorFlow with pip  |  TensorFlow worked for me

I was getting exactly the same error installing tensor flow with python3.5. Installing into a virtual environment as per the link worked. So it must have been a conflict with some other packages.

Since tensorflow 1.9 supports raspberry pi, if you follow this link, this much is what is required to do. 

sudo apt install libatlas-base-dev
pip3 install tensorflow

you can check the installation by running this code. 

import tensorflow as tf
tf.enable_eager_execution()
hello = tf.constant(‘Hello, TensorFlow!’)
print(hello)

I already this sudo apt install libatlas-base-dev code and it is up to date. when i run the pip3 install tensorflow it give me above error
please check if you have urllib3 installed? if not install it and try it again
When I use sudo pip3 install tensorflow it is installing but can not add that library. when i use pip3 install tensorflow can not install get above error
these are not errors but runtime warning, please check with the code in the updated answer, runtime warning arises due python 3.4 a and 3.5, dont worry about these warning your tensorflow is now working which means urllib3 was the issue. please upvote my answer if my suggestion helped you!
I got this tf.Tensor(b'HelloTensorFlow', shape=(), dtype=string). Is it fine?
