There is an error in operation. I would like to ask you for help.

Hello, thank you for providing such an excellent project and code. I don’t understand something and would like to ask you for advice. After configuring the api, I ran the command tracarbon run in the terminal but an error was displayed. I would like to ask you for advice on which one should be run. Does the program or what other parts of the program need to be changed before it can run?
error：
ValueError: could not convert string to float: ''

Hello @AceWang377 👋,

Thank you for your message!

Sure, I can help you with that. However, I'll need some more information to provide a detailed answer:

1. The version of Tracarbon
2. The full stack trace, I would need to see the error message you're receiving. If you're running a command or a script that results in an error, please provide the entire output.
3. Regarding the hardware, could you please specify what information you're interested in? Are you asking about the server specifications (like CPU, RAM, etc.) or something else?
4. As for where it's running, are you asking about the physical location of the server or the type of environment (like production, staging, etc.)?

If you could provide these details, I'd be able to assist you better.

Thank you very much for replying to my message. I'm just learning this stuff so I'm sorry I have some very basic questions for you. My computer is the MacBook M1 version, and yesterday I entered the variable environment TRACARBON_CO2SIGNAL_API_KEY=", then pip installed some necessary packages, and downloaded the software Developer Portal by Blobr. Then run all the code in your code package. py file is also not an error. But when I finally ran tracarbon run in the terminal, an error occurred:

1.Tracarbon version is 0.7.1
2. The error is as shown above
3/4. Please forgive my ignorance. I want to use this carbon footprint software to record the carbon emission index generated by my daily behaviour, and use this to check the carbon emission level in my area. Then after downloading the DEVERLOP software, I can directly use the map to see the average carbon emission level in my area, but I don't know if it can also record my carbon footprint.

Thank you again for taking the time to answer my question, and I look forward to hearing from you.

Thank you @AceWang377!
Could you please run this command in a terminal on your laptop:
/usr/sbin/ioreg -rw0 -c AppleSmartBattery
And send me the full output in text with the command used.

If the output is too big:
/usr/sbin/ioreg -rw0 -c AppleSmartBattery | grep BatteryData | grep -o '"AdapterPower"=[0-9]*'

I will take a look on why it fails on your Mac.
