通过 python3 pip 在 linux 上运行 tensorflow

Question

I have installed python and tensorflow on my linux, This is my all step that I done:

sudo apt install python3 python3.pip
sudo pip3 install ––upgrade pip
pip3 install ––upgrade setuptools
pip3 install tensorflow
pip3 install keras

This version of tensorflow and keras is installed:

Alt@mx:/mnt/Project/ML/AE
$ pip3 show tensorflow
Name: tensorflow
Version: 2.4.0

And:

Alt@mx:/mnt/Project/ML/AE
$ pip3 show keras

I create a simple code on vscode:

import tensorflow as tf
hello = tf.constant("Hello, TensorFlow!")
sess = tf.Session()
print(sess.run(hello))

But when I run it by vscode I got:

Alt@mx:/mnt/Project/ML/AE
$ /usr/bin/python3 /mnt/Project/ML/AE/simple_auto_encoder.py
Illegal instruction
Alt@mx:/mnt/Project/ML/AE

What is my mistake?

Answer 1

This problem may refer to the instruction set that the binary supports. Check the compatibility with your CPU. For more information check this .

I would also like to mention that you don't have to install separately the keras library because it is included in tensorflow .
