Tensor Flow for Poets | Restarting docker | invalid reference format

I'm new to trying out Tensorflow for Poets. I followed the instructions to create my own image classifier. But I am getting an error following step 3 of the tutorial in here

When I ran the following command in PowerShell:

docker run -it \ - publish 6006: 6006 \ - volume $ {HOME} / tf_files: / tf_files \ - workdir / tf_files \
Tensor Stream / Tensor Stream: 1.1.0 bash

I am getting the following error:

C: \ Program Files \ Docker \ Docker \ Resources \ bin \ docker.exe: Invalid reference format. See "C: \ Program Files \ Docker \ Docker \ Resources \ bin \ docker.exe run --help

I tried to pass home address instead of $ HOME, tried even lowercase code for the address. But still I am getting the same error.

I would be grateful for thoughts and suggestions.

Thank!
