Install with GoLang
This method of install is more flexible & allows you to run it on any machine (Linux/Mac/Windows)
In order for it to work you need to have Go installed. It also requires you to have required libs (libtesseract) available on the system, as this method is actually compiling a binary from source.
This method will work fine on different architectures (arm64) too. So you can use it on Raspberry PI.
