Put API key file in the fixed .PyMOL folder in the home directory to avoid...

1. Download the plugin script `chatmol.py` and save it to a convenient location on your computer.

2. Open PyMOL.

3. In the PyMOL command line, enter `run /path/to/chatmol.py` (replace `/path/to` with the actual path to the script).

4. The plugin is now installed and ready to use.

4. Create a .PyMOL folder in your home director for saving PyMOL related files, like ChatGPT API keys, PyMOL license file etc.

5. The plugin is now installed and ready to use.

Alternatively, you can use the following command to load the plugin directly:

conversation_history = " "    

stashed_commands = []

PLUGIN_DIR = os.path.dirname(os.path.abspath(__file__))

API_KEY_FILE = os.path.join(PLUGIN_DIR, "apikey.txt")

# Save API Key in ~/.PyMOL/apikey.txt

API_KEY_FILE = os.path.expanduser('~')+"/.PyMOL/apikey.txt"

OPENAI_KEY_ENV = "OPENAI_API_KEY"

def set_api_key(api_key):

    api_key = api_key.strip()

    openai.api_key = api_key

    print("APIKEYFILE = ",API_KEY_FILE)

    try:

        with open(API_KEY_FILE, "w") as api_key_file:

            api_key_file.write(api_key)

def load_api_key():

    api_key = os.getenv(OPENAI_KEY_ENV)

    print("APIKEYFILE = ",API_KEY_FILE)

    if not api_key:

        try:

            with open(API_KEY_FILE, "r") as api_key_file:

def start_chatgpt_cmd(message, execute:bool=True):

    global stashed_commands

    global conversation_history

    message = message.strip()

    execution = True

    if (message[-1] == '?'):
