I\'m trying to intstall TensorFlow using pip:

If you run into this issue recently (say, after Python 3.7 release in 2018), most likely this is caused by the lack of Python 3.7 support (yet) from the tensorflow side. Try using Python 3.6 instead if you don't mind. There are some tricks you can find from https://github.com/tensorflow/tensorflow/issues/20444, but use them at your own risk. I used the one harpone suggested - first downloaded the tensorflow wheel for Python 3.6 and then renamed it manually...
cp tensorflow-1.11.0-cp36-cp36m-linux_x86_64.whl tensorflow-1.11.0-cp37-cp37m-linux_x86_64.whl
pip install tensorflow-1.11.0-cp37-cp37m-linux_x86_64.whl
The good news is that there is a pull request for 3.7 support already. Hope it will be released soon.
