Added requirements for engage examples and corrected paths in chatGPT_example.

Adding requirements and correcting the paths resolves issues in 3/4 engage examples.
example_Generative_Engage.py still has issues with CUDA.

Testing on a intel-based Mac:

• Example chatGPT: works, but I am not sure how to properly test the chat. If you do @oliver93mk, tell me and I will write it down in a Information GUI, for all to know.
• Example scene shape classification: works, but I will add an information GUI, to describe what it does, as well as print the results in the GUI (currently they are only shown at the terminal)
• Example generative Engage : returns a 27210 segmentation fault as soon as it is run.
• Example Link Prediction: returns a 27429 segmentation fault as soon as it is run.

For Example chatGPT users need to insert their openAI key in the chatGPT.py file. In this case, chatGPT acts like an authoring tool with text, you can ask it to move objects around.

Example Link Prediction: works fine on windows. It simply trains different types of Auto Encoders

@aprotopsaltis Please check

• OpenAI API Key was entered in ChatGPT.py
• Scene generates ok
• When entering a command to "move the cauterizer exactly on top of the table" (as in the commented description) the system becomes unresponsive
• OpenAI reports that the API Key was used successfully

Same here (same intel-based mac)

there is no way we ask users to enter their chatGPT key. Check pyEEL 2.8 example:
openai.api_key = os.getenv("OPENAI_API_KEY")
