WS2813 ledstrip

how can you install this device properly, i already tried a lot what i found online but so far no luck.

Device: RPI3 + Grove base + WS2813 ledstrip
by this curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -
I dind’t get it right so then i did.

git clone https://github.com/Seeed-Studio/grove.py
cd grove.py
sudo pip install .
sudo pip3 install .

i got this installation now. i can open the maps but when i try to run.
sudo grove_ws2813_rgb_led_strip.py
it returns that there is nothing like that.

sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --       

Really can’t understand it. when i bought the led it says plug and play. but after spending a lot of time it still won’t do anything.
Thanks in advance!

If you use the I2C tool to scan the I2C address of the Grove module, you may find the address of the Grove Base Hat for Raspberry Pi. The absence of the Grove Base Hat address means that the firmware has not been installed successfully.
We are sorry to bring you an unpleasant experience. At present, we do not provide the application of WS2813 ledstrip on the Raspberry PI. Thank you for your understanding and support
