Hey, First of all I see that you need a numpy package so I assume some matrix/tensor operations are done. There is no difference in performance between R and Python if you are using proper BLAS and LAPACK. Windows users might use MRO MKL, Linux users openblas and the Mac os vecLib has to be activated. I done some benchmarks some time ago, https://github.com/Polkas/RPbenchmarks. Unfortunately they are done only partly.
If we talking about system requirements as i see you need only python and a one library numpy. As i remember rsconnect using python script and do not need any additional system requirements. https://github.com/rstudio/rsconnect/blob/main/inst/resources/environment.py. they run it if python is available, if not other code is executed. Have a nice day.
