I2cdetect problem, thermometer python jetson nano, pip3

I have a few questions.

Now, first of all, I started using and learning jetson nano. I had a problem during the installation phase. Spidev files are supposed to exist but do not exist. I tried to install with pip3 by applying the solutions I found, but it is still not available and I get a different result in i2c detect. I followed the steps on this site Initial Setup | CircuitPython Libraries on Linux and the NVIDIA Jetson Nano | Adafruit Learning System.

I can’t continue my project.

-desktop:~$ sudo i2cdetect -y 1

[sudo] password for **:

I am getting errors in my python codes. I keep getting errors even though the library is available. I’m using Spyder and it’s telling me to install ipykernel and cloudpickle. I installed it and when I do pip3 list I can see it but it still doesn’t work. What should I do?

I want to measure instantaneous temperature values ​​in a simple way using MLX90614. Can anyone give code as an example?

Thank you from now.

You can use i2c utils like i2cget to verify the HW first.
