Keras installation error

Hello,

Now you can finally install Keras, with the commands devtools::install_github("rstudio/keras") - library('keras') - install_keras().

after i followed the above line and any prior lines which is in manual (https://manual.zorro-project.com/deeplearning.htm)
installation started and finally at the end i got a msg saying that
Error in devtools::install_github("rstudio/keras") - library("keras") :
non-numeric argument to binary operator in RStudio

screenshot of the error is attached to this post.

Would you please tell me how to correct this?
I tried running the deeplearning script in strategy in Zorro got error,

screen shot of zorro is attached.

Thank you .

also there is cmd window popping up.

By the way, this below line is from the manual (https://manual.zorro-project.com/deeplearning.htm)

Edit Zorro.ini and enter the path to the R terminal on your PC, f.i. "C:\Program Files\R\R-3.6.1\bin\x64\Rterm.exe".

i can't find rterm.exe in my zorro installation. how do we get around this?

I think this might cause my initial problem.

Can anyone help me with this error?

The error message looks like an error in the install_keras function. Either you you entered something in a wrong way, or the installer is incompatible to your R version or to some other library. In that case there will be likely soon a fix. Check on
Keras or R forums how to install keras nowadays, or if such a problem is known.
