title: Can't find conda at rstudio terminal, while it is workable outside?
body: <p>Just trying to use tensorflow-gpu on my notebook, after installing anaconda, VSC++, CUDA, cdnn, and then tensorflow-gpu on conda base environment.
  Before the gpu version, I'd using keras(cpu) for a while, so the cpu version is installed, and running well.</p>
  
  <p>My question is, why I can't find r-tensorflow environment, even the <code>conda</code> commend in the rstudio terminal does not exist.</p>
  
  <p>the rstudio terminal windows</p>
  
  <pre><code>eric1@NB  /g/work/R_Prj/KEK/2019-08-TEST (master)
  $ conda
  bash: conda: command not found 
  </code></pre>
  
  <p>the Anaconda prompt window</p>
  
  <pre><code>(base) C:\Users\eric1&gt;conda info --envs
  # conda environments:
  #
  base                  *  C:\Users\eric1\Anaconda3
  </code></pre>
  
  <p>and both on the same notebook at the same time.
  Please advise how I can see conda in the rstudio, and how I can install tensorflow-gpu version in R. Many thanks.</p>
