python in r: pandas not found

Question

I am trying to improve my research by the combining of R and Python advantages. Reticulate package is a promising tool for this purpose. But something comes wrong...

devtools::install_github("rstudio/reticulate")
library(reticulate)

py_available()

[1] FALSE

py_config()

python: /usr/bin/python

libpython: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config/libpython2.7.dylib

pythonhome: /System/Library/Frameworks/Python.framework/Versions/2.7:/System/Library/Frameworks/Python.framework/Versions/2.7 version: 2.7.10 (default, Oct 23 2015, 19:19:21) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)]

numpy: /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy numpy_version: 1.8.1

python versions found:

/usr/bin/python

/usr/local/bin/python

/usr/local/bin/python3

/Users/User/anaconda/bin/python

use_python(" /Users/User/anaconda/bin/python")

I am using all "data science pack" under Anaconda. Thet is why the corresponded python version was chosen. All required packages are installed and they often in use via Jupiter notebook

py_available() 

[1] TRUE

Yes, as expected!

py_module_available("pandas")

[1] FALSE

Not available for some reason(((

Thank you in advance for the ideas))

SessionInfo for a case:

Answer 1

You need to set the second argument of the function, so it should be:

For expample use_python("/users/my_user/Anaconda3/python.exe",required = TRUE)

DONT forget the required = TRUE

Answer 2

I think you have to call use_python immediately after calling library(reticulate), before py_config or anything else.

That worked for me. More details in this question: Importing python module in R
