Monitoring Ryzen 2700X CPU Temperatures in Ubuntu 18.04 (Kernel 5.0.11)

How can we monitor the CPU temperature of an AMD Ryzen 7 2700X in Ubuntu 18.04? The kernel has already been updated to 5.0.11-050011-generic, yet sudo sensors-detect shows nothing being detected, and sensors do not show CPU temps.

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
