reaching python with R -


i trying install tensorflow in rstudio, when run install_tensorflow(), get

error: prerequisites installing tensorflow not available.  execute following @ terminal install prerequisites:  $ sudo pip install --upgrade virtualenv

but virtualenv installed.

i don't konw thing python.

i using osx.

which python outputs

`/home/name/.pyenv/shims/python`

but when going python console, 

python 2.7.10 (default, dec  3 2015, 00:46:36)  [gcc 4.2.1 compatible apple llvm 7.0.0 (clang-700.1.76)] on darwin type "help", "copyright", "credits" or "license" more information. >>> import sys >>> sys.executable '/home/name/.pyenv/versions/2.7.10/bin/python'

system("python --version") in rstudio outputs

python 2.7.10

so tried put in .rprofile 

sys.setenv(path = paste("/home/name/.pyenv/versions/2.7.10/bin/python", sys.getenv("path"), sep=":"))

or 

sys.setenv(path = paste("/home/name/.pyenv/shims/python", sys.getenv("path"), sep=":"))

besides, see tensorflow packages indeed installed

/home/name/.pyenv/versions/2.7.10/lib/python2.7/site-packages

someone has idea ?

update:

since python tensorflow package installed in system, located under /home/name/.pyenv/somepath/, tried run tensorflow function directly inside rstudio , got this

error: installation of tensorflow not found.  python environments searched 'tensorflow' package:  /usr/bin/python  can install tensorflow using install_tensorflow() function.

knowing running sys.getenv() in rstudio gives correct path

path /home/name/.pyenv/versions/2.7.10/bin/python:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/x11/bin:/usr/texbin:/opt/local/bin

update 2

now, think beginning locate problem. forced rstudio use version of python when run sys.executable '/home/name/.pyenv/versions/2.7.10/bin/python'

so use_python("/home/name/.pyenv/versions/2.7.10/bin/python")

now, when run tensorflow function

error: python module tensorflow not found.

detected python configuration:

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 tensorflow:     [not found]

it seems rstudio doesn't take account version want use

solution : find problem came , how tackle it, here

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...
