I downloaded some msvdp71 zip file and extracted it and copied it in my sys32 and syswow folders it didnt work for me.In colab i trained few models and i want to run them on pc when i try to run them with tf1.6.0 they gave errors related to version .so when i upgraded it using pip i was not even able to import it.

回答1:

Create a virtual environment in python. For the creation of a virtual environment, you need virtualenv library.

pip install virtualenv

After installing create your virtual environment.
command - virtualenv "NAME-OF-ENVIRONMENT"

eg

virtualenv myenv

This will create a directory called myenv. To activate the virtual environment you have go inside the myenv/scripts folder, open a cmd prompt and type activate.

eg

cd myenv/Scripts
activate

Get out of the Scripts folder

cd ../..

Now install TensorFlow.

pip install tensorflow

Tensorflow requires various libraries to work. As you know TensorFlow 1.x and 2.x are not compatible. When you ran the upgrade script it must have only upgraded the version and not downloaded the dependency.

Note: Always create a virtual environment when working in any project and keep your python package clean. You can delete these environments if they become corrupt or stop working correctly due to any reason, without and fear.
