tfp and tf version mismatch

melondonkey commented 4 years ago

I'm having a lot of trouble with installation and running a simple example. I have tried to manually specify the tensorflow version by install_tfprobability(tensorflow='2.1.0') but it created other problems? Shouldn't the install function select a tensorflow base that will work out of the box?

library(tfprobability)
#> Warning: package 'tfprobability' was built under R version 3.6.3
install_tfprobability()
#> 
#> Installation complete.
library(tfprobability)

d <- tfd_binomial(total_count = 7, probs = .3)
#> Error: ImportError: This version of TensorFlow Probability requires TensorFlow version >= 2.1; Detected an installation of version 2.0.0. Please upgrade TensorFlow to proceed.
#>

Same problem, cannot see a TensorFlow version >= 2.1 neither in CRAN nor in https://tensorflow.rstudio.com/

Sorry, this one got overlooked...

You're right,

install_tfprobability()

should just work. As of today, it should install TensorFlow 2.1. And as soon as https://github.com/rstudio/tensorflow/pull/416 will have been merged it will :-)

Until then, please execute

install_tfprobability(tensorflow = "2.1")

instead.

rstudio / tfprobability
