Fault in reticulate in rstudio - anaconda

476/5000
rstudio generates error when running R code with python code. At first the code worked very well but in the second installation it started to generate faults. Here is the link of the code in case you want to play #https: //www.r-bloggers.com/r-and-python-using-reticulate-to-get-the-best-of-both-worlds/
. My laptop is hp 4 gigs of ram and 500 mb of hard disk.
I would greatly appreciate who can explain the failure and how to solve it.
I have reinstalled anaconda last version twice.
library(reticulate)
use_python("/usr/local/bin/python")
use_virtualenv("r-reticulate")
os <- import("os")
Error: lexical error: invalid char in json text.
WARNING: The conda.compat modul

Error: lexical error: invalid char in json text.
WARNING: The conda.compat modul
(right here) ------^

Actually, it comes from a deprecation warning reported a few days ago (fix compat import showing warning #8507).
But the fact is that this warning in "conda.compat" generates some errors, for example in the case of using conda environments in R through "reticulate" functions. This issue has been reported quite recently Conda warnings taken as errors #477.
The solution is to simply install the github version of "reticulate" in order to avoid these errors and ignore the conda warnings which shouldn't necessarily impede these functionalities. You can do it like this way:
remotes::install_github("rstudio/reticulate")
And don't forget to have the latest Rtools installed in your operating system!

This might be useful for you: https://docs.anaconda.com/anaconda/user-guide/tasks/switch-environment/
I have Anaconda, and set up Python 2 environment. Once activated, run 'use_python' with the path to that environment and set the 'required' parameter to TRUE.

I had the same problem. I solved the problem by installing an older version of conda.
In anaconda promt
conda install conda = 4.1.6

Octave: error installing package on Windows

First of all, I know a lot of questions similar to mine have been asked, and nevertheless they don't help me solve the problem I'm facing. I'm running Octave 5.1.0.0 on Windows 10 Pro 64 bit. I'm having no issues but one: when I try to install Symbolic package by pkg install symbolic-2.7.1.tar.gz (downloaded from Octave Forge), I get the error
unpack: unarchiving program exited with status: 1
tar: Error opening archive: Failed to open
'/C/Users/smlvcfncst/Downloads/symbolic-2.7.1.tar.gz'
error: called from
unpack at line 274 column 5
untar at line 48 column 5
install at line 81 column 9
pkg at line 441 column 9
and I have no clue where the problem related to the unpacking could be. Not only I have 7z and Winrar installed, but moreover I use a full installation of Cmder, so my system has everything that is needed to work with a .tar.gz
I've tried in different terminals, both with and without administrator privileges, and the problem persists. How should I proceed then?
EDIT: Following Andy's suggestion, I let you know that even before installing Octave I already have installed and used both Python and MinGW, as well as sympy module. Moreover, my Octave installation was the most standard possible for Windows, that is using the official .exe installer. No other package, apart from those included with installation, have been added before I tried adding symbolic.
Thank you in advance.

pyinstaller gives weird errors when compiling pandas

UPDATE june 18:
I would like compiling my python code for windows.
I use to work with pyinstaller, python 3.5+, windows 7 and anaconda to control modules pandas, pyqt (v5) and pyqtgraph, but it seems something is not compatible. I would not be surprised if you tell me to change a version.
In previous versions, it worked with python 3.5, windows 7 and Pyinstaller 3.3.1- without pandas; the new version imports pandas and then this doesn’t work anymore:
with the usual config pyinstaller gives a message saying the C libraries are not built. Following the instructions, I should run python setup.py build_ext --inplace --force, except I don’t see the setup.py file, so I don’t know what to do. Forums tell me it should be a problem with pip but not with conda… but I use conda…
with python 3.6, I got an error message ‘RecursionError: maximum recursion depth exceeded’ (https://github.com/steph2016/profiles/blob/master/errorMessage). This problem seems known and solutions I found on forums is either to downgrade python or to replace my PyInstaller-3.3.1 by PyInstaller-3.4.dev0+7b3143612. But with PyInstaller-3.4.dev0+7b3143612 I get a ’’str’ object has no attribute ‘items’’ error (https://github.com/steph2016/profiles/blob/master/ErrorMessage2). I’m not sure pyinstaller is compatible with python 3.6…
with python 3.4, I got an error similar to the ‘str object’ one above. I’m not sure python3.4 is compatible with qt5…
I would be pleased by any solution with any version of whatever to windows-compile my code
I don't know if it is the issue but I didn't find PyQtGraph in Supported-Packages
I eventually applied the first solution proposed in No module named 'pandas._libs.tslibs.timedeltas' in PyInstaller in the original config (python 3.5, PyInstaller 3.3.1, pyqtgraph, pandas, windows 7,...) and it worked.
I don't know why adding def get_pandas_path ..... a.binaries) helps, so I can't justify. But just to be explicit even if it seems obvious: pyinstaller must be run on the spec file, not on the py one (for instance > pyinstaller toto.spec)

Installing Perl and PDL

I am currently trying - unsuccessfully to install perl PDL as I would like to automate some of my data analysis and graphics generation.
Unfortunately I seem unable to even install the necessary modules without issue, let alone create a small script to deal with my data files.
I have some rudementary experience with Perl but Nothing fancy and am using Windows 10 x64.
Initially I went for the x64 strawberry perl v5.24 installation, followed by ppm installations of Astro::FITS::Header, Convert::UU, OpenGL and PDL - as instructed here http://pdl.perl.org/?page=install. However, there were issues with the installation of Inline::C and after trying the example listed on page 5 of the PDL_Book_Latest http://sourceforge.net/projects/pdl/files/PDL/2.4.10/PDL-Book-20120205.pdf/download there wasn't any image appearing, nor image file in any location I could think to search. Back to Google and still no luck finding any information on the source of this issue so I decided to go back to square one and use an older version in the hopes that it would be more well documented.
So, uninstallation of strawberry perl through Windows installed programs dialog, deletion of strawberry folder and registry entries containing "strawberry". Then a new installation of perl, with the Padre IDE, v5.14 - maybe some debugging fonctionality will help pinpoint the errors. Started installing the same modules (Astro::FITS::Header, Convert::UU, OpenGL, PGPLOT). Astro and Convert worked fine, but the OpenGL started throwing errors about ExtUtils::F77 which I am apparently missing after a few more hours searching. I go to install this module and it keeps giving errors about 'gfortan' being an unknown command... It was my understanding that the idea of PDL was to avoid fortran and C, and I have found next to no information about this installation problem so far.
So i decided to try an alternative approach. I installed the ppm module from cpan and repeated the initial installation process through the ppm command. This time i get:
"Unknown element 'PROVIDE' found inside SOFTPKG. at C:/Dwimperl/perl/site/lib/PPM.pm line 1462."
So my question is as follows:
Am I missing some critical step in the installation process? Is my system just handing this really badly, and if so is there any sort of possible work around? Is the fact that I tried two different versions liable to create path issues that could be at the root of this problem?
Could anyone provide an alternative and preferably not too complex route to install PDL with a given perl installation on Windows 10?
EDIT 1:
Here is the code for the error I got trying to install Inline::C, an apparent pre-requisite for PDL
code deleted to make space for updates...
EDIT 3:
I reinstalled GnuWin32 in the directory specified by PATH, rather that changing PATH, and the tried the installation again. Inline::C gave the same 'diff' and 'rm' errors. So i ran "cpanm --notest 'package'" to install Inline::C and then PDL, both said they were successful. However, even using '--notest' cpanm could not install OpenGL and PGPLOT.
The final objectif is to be able to produce graphics using the fonctions from PGPLOT: for example
# use PDL;
# use PDL::Graphics::PGPLOT;
# imag(sin(rvals(200,200)+1));
yet this doesn't work of course if PGPLOT can't install.
EDIT 4:
Tried the fix found by #Dr.Avalange at sourceforge https://sourceforge.net/p/pogl/bugs/26/ and noticed that I seem to have multiple copies of this file.
Here
Is this normal...?
EDIT 5:
So i uninstalled perl, deleted any lingering files I could find in %APPDATA%, %USERPROFILE% and C:/DWIM, and then ran ccleaner just in case I missed anything.
I then downloaded Strawberry perl 5.24.1 x64 for Windows and installed it.
After this, I ran 'cpanm Astro::FITS::Header', cpanm 'Convert-UU' and 'cpanm OpenGL' as per http://pdl.perl.org/?page=install. This all worked fine. Then I ran 'cpanm PDL' which installed Inline, Pegex, Win32::Mutex and Module::Compile dependencies. However, if had the same error with Inline::C that you mentioned previously.
I already had GetGnuWin32 installed before so not sure why this isn't working. The Windows 'Path' environment (not PATH - this doesn't exist according to the advaced system dialogue) is noted as
%USERPROFILE%\AppData\Local\Microsoft\WindowsApps;
In this directory I have the folder GetGnuWin32 which should have installed all the packages from the link you provided, unless there is a supplementary step that I missed to install this correctly? So I redownloaded the DiffUtils setup and ran that, installing to \programfiles(x86) (default option). I then reran 'cpanm PDL'.
I still get the same 'diff' error message. So is DiffUtils, not installing properly? (I did close and re-open the commandline between tries and after the installation)
EDIT 6:
So after installing PDL and PGPLOT with --notest I tried to run the following test and it failed. See below

There was already a directory problem but I managed to point it in th right direction I had thought. Also tried installing the PLplot 'cpanm' said the installation was successful but there is no .pm file, only a .pd in another directory and so the use PDL::Graphics::PLplot fails as there is no .pm file to find.

So retrying ppm install http://www.sisyphusion.tk/ppm/PGPLOT.ppd seemed to work this time as the links int he explanation you provided are no longer in use

After translating from French I can see that you don't have diff in your system. Either install diff (part of gnu32: http://gnuwin32.sourceforge.net/) or just skip the tests. See also:
https://github.com/ingydotnet/inline-c-pm/issues/60
With Strawberry 5.24.1 simply type the following from the command prompt:
cpanm --notest PDL
or if you want to watch everything that's going on:
cpanm -v --notest PDL
This will take some time to run.

Clojure fireplace in vim asking for python

Trying to get get fireplace set up in vim but having trouble with some error messages.
When I type cpr in a clojure buffer the following error shows up:

The thing I understand is that it cant find python. In my shell I can start python with the python command which will fire up 3.4.2.
Im using nixos
:echo has('python') returns 0
echo $PATH and :! echo $PATH return the same path.
What can I try in order to find what is actually causing this error?
You have to install/compile vim with python support for vim-fireplace to work, and this may not be the default on your system. I believe typing :help python will do this for you. If you don't get anything, you may have to recompile vim with python support, for which I'll direct you towards Google for now.
Another option if you have pip installed is to consider switching to neovim. Installing neovim with pip install neovim will get you python support. I've been using neovim lately, and it's worked pretty well for me.

Help Installing psycopg2 on snow leopard : command '/usr/bin/gcc-4.0' failed with exit status 1

This has been driving me crazy for 2 days.
I have been trying to install psycopg2 using easy_install and no matter what I try (i.e using gcc-4.0 instead of the snow leopard default one) I always get the same error:
error: Setup script exited with error: command '/usr/bin/gcc-4.0' failed with exit status 1
Please see: http://dpaste.com/hold/228252/
I have googled that error so many times and nothing I have found seem to help.
Looks like you're missing a dependency, the development files for libpq. The relevant log part is here:
In file included from psycopg/psycopgmodule.c:32In file included from psycopg/psycopgmodule.c:32:
./psycopg/psycopg.h:31:22: error: libpq-fe.h: No such file or directory
Try installing libpq development files and then rerun easy_install. You may hit another missing dependency; pay attention to the first error that GCC spits out.
Link http://dpaste.com/hold/228252/ seems to be dead, this is how I solved this problem (Mac OS X 10.6, virtualenv).
If pip fails with this message, just take a look to build folder in your virtual environment. You should edit setup.cfg file there, particularly include_dirs and library_dirs. In first one set your include folders, my option was:
include_dirs=/opt/local/include/postgresql84:/opt/local/include/postgresql84/server
and most likely you will need to set library_dirs to correct location as well:
library_dirs=/opt/local/lib/postgresql84.
probably you should install postgresql-devel first
yum -y install postgresql-devel
