But the script works and display the accuracy but this part above show before the runs. Do you have any idea , I install tensorflow on anaconda :
回答1:
The above warning is thrown because TensorFlow library was originally compiled on different architecture machine and is not optimized for your particular architecture. Which means that it will continue to function, but you won't be getting max performance out of the library.
To get the max performance on your machine, you need to build TensorFlow on your machine.
Refer to the official documentation for the steps for building from source.
