Float division zero error for MLX90641 with RasPi3

Hi Seeed Studio Team,

Thank you for your support.

I am testing 101020992 with connecting to Raspberry Pi 3.
The connection image is as follows.


I connected it to a Raspberry Pi and ran Getting Started by Raspberry Pi, which is

published by seeed studio, to check its operation.
When I entered the command 「sudo ircamera I2C MLX90641」and ran the Python code, I got a error「float division by zero」

Investigating the cause, we found that 0x2427[kVdd] is 0. Is this the cause?

If this is the cause,
Can you give some advice for why this happened and what should we do for it?
