GrovePi's FORUM was so quick that I asked a question and got an answer in __28 minutes __! In this industry, where it takes about two weeks to get a meaningful answer and paid support is the norm, the development of this one stops during that time, and I really appreciate this kind of quickness. In my case, I often find the "speed" of this QA more attractive than the function, quality, and performance of products and services, or I feel reassured that "this is okay to use."
The cause is that smbus wasn't available in python ... Read the error message properly, and I'd be scolded by the Japanese mailing list ... Thanks to Exadon for his kindness!
The procedure you taught me
sudo apt-get install python-smbus
sudo apt-get install i2c-tools
Also, check if I2C is enabled in raspi-config
