feature_spec fatal error and closse R (Rstudio)

[gustavoveloso]

I am trying exemple

https://tensorflow.rstudio.com/guide/tfdatasets/feature_spec/

when I run the command:
spec <- feature_spec(hearts_train, target ~ .)

There is a fatal error in Rstudio, closing the session.
Windows version :
Windows 10 pro

Rstudio version :
Version 1.2.5019

R version :
R version 3.6.1 (2019-07-05)

And RStudio now sees Python:
version: 3.6.10 |Anaconda, Inc.| (default, Jan 7 2020, 15:18:16) [MSC v.1916 64 bit (AMD64)]
Architecture: 64bit
numpy_version: 1.18.1

Also RStudio can see conda version:
conda_version()
[1] "conda 4.7.12"

tensorflow version :
version = "2.0.0"

Thank you for your help.
