how to do uvc-radiometry.py

[ghost]

Ubuntu environment(20.04) user name is kang, so in /home/kang path
git clone https://github.com/groupgets/libuvc
cd libuvc
mkdir build
cd build
cmake ..
make && sudo make install
I carried out this command.

And I entered the 'python3 uvc-radiometry.py command',
file "uvc-radiometry.py ", line 4, in module from uvctypes import * modulenotfound error: no module named 'uvctypes' " has appeared.
What's the problem ?
And I'm Ubuntu 20.04 version, and I've connected lepton3.5 with purethermal3.
