python 3.9 中的 Tensorflow 安装错误：无法安装 tensorflow [WinError 2]

Question

While installing TensorFlow on Windows having python 3.9 installed using the following command:

pip install tensorflow

Following error occurred with the warning:

WARNING: Failed to write executable - trying to use .deleteme logic

ERROR: Could not install packages due to an OSError: [WinError 2] 
The system cannot find the file specified: 'c:\\python39\\Scripts\\pyrsa-decrypt.exe'
-> 'c:\\python39\\Scripts\\pyrsa-decrypt.exe.deleteme' 

How this can be resolved?

Answer 1

Run the same command using

--user

pip install --user package_name

or you can try to restart the terminal and run it as admin

Answer 2

Just run the cmd as an administrator then retype the command pip install tensorflow it will take over from where the error occured.

Answer 3

What seems to be working for me on Windows Python 3.9 is:

pip install --upgrade tensorflow

Just to get it to install without an error.

As mentioned in the documentation . Its even working for a non virtual env on my end.

Answer 4

In my case: When I am running google colab in local runtime jupyter, I tried next command and it worked for me:

!pip install --user tensorflow
