Most of the problems people are having are already described in the installation instructions.

You should first make a serious attempt to solve your problem. If you ask a question that has already been answered elsewhere, or if you do not give enough details about your problem, then your issue may be closed immediately. Please don't waste my time!

These tutorials were developed in Python 3.5 and may give strange errors in Python 2.7

You need to download the whole repository, either using git clone or as a zip-file. See the installation instructions.

General questions about TensorFlow should either be asked on StackOverflow or the official TensorFlow repository.

The tutorials cannot change too much because it would make the YouTube videos too different from the source-code.

These tutorials were made by a single person on his own time. It took a very long time to research and produce the tutorials. If a topic is not covered then the best thing is to make a new tutorial by yourself. All you need is a decent microphone, a screen-grabbing tool, and a video editor. I used the free version of DaVinci Resolve.

Please carefully read the installation instructions and only open an issue if you are still having problems.
