In order to realise some course's activity in Octave, found in the following site
https://nbviewer.org/github/gpeyre/numerical-tours/blob/master/matlab/audio_1_processing.ipynb#
I needed to install some toolboxes found in
http://www.numerical-tours.com/installation_matlab/
Two of them seems to be easily installed via pkg install -forge ... (I have Linux Mint 19), these toolboxes are 'general' and 'signal', but 'graph' and 'wavelet_meshes' seems not to be directly available for Octave.
1 - So, if I downloaded them manually.. how should I install these packages? I do not even find Octave directory using 'whereis' in order to localise a proper folder to throw toolboxes files (its path shown located in /app/share/octave when open).
2 - Another thing.. should I spect to use toolboxes automatically after toolbox is installed? or may I indicate its selection in some specific way? ..I ask this because after running the following script chunk
n = 1024*16;
options.n = n;
[x,fs] = load_sound('bird', n);
command window throws the following message
error: 'load_sound' undefined near line 3, column 4
so I understand Octave does not recognises 'load_sound' function, which is from 'signal' toolbox (that is already installed).
Any suggestions?

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.

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
(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!

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
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.
EDIT: 7
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

http://jrfonseca.home.dyndns.org/projects/gnu-win32/software/ported/patches/pgplot-5.2.2-mingw32.diff.gz
And while this seemed to work, there are no traces of the files that were listed as necessary for the installation, unless they were just for this specific method?

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.
I have a Python 2.7/PyQt4 program that I am attempting to freeze with cx_freeze. The program also uses requests, serial, xml.etree.ElementTree, and collections. Using the unmodified setup.py generated by cxfreeze-quickstart-2.7, I can successfully build as both a console program (python setup.py build) and an .app (python setup.py bdist_mac) in Yosemite using Python from macports. If I run the program directly either from the app bundle or the dist:
$ build/MacDISE-1.0.app/Contents/MacOS/macdise
$ dist/macdise
It runs exactly as expected. If I open from the command line:
$ open -a /Users/jeffemandel/macdise/build/MacDISE-1.0.app
I get the dreaded
LSOpenURLsWithRole() failed for the application /Users/jeffemandel/macdise/build/MacDISE-1.0.app with error -10810.
I worked through a number of potential issues raised by Dan McCombs (distutils.util.get_platform, sys.arg), but these don’t seem to be the problem. Through brute force trial and error, I found that if I put all of my code in a separate module, simply importing that module (without actually invoking it) causes the 10810 error, so I figured it was finding a library when run from the command line, but not from the app. I put the dist directory on a thumb drive and ran it on another Mac that doesn't have Python, Qt4, etc installed, and got this:
packages/cx_Freeze/initscripts/Console.py", line 27, in <module> File "macdise.py", line 4, in <module>
File "ExtensionLoader_PyQt4_QtGui.py", line 11, in <module>
ImportError: dlopen(/Volumes/NO NAME/dist/PyQt4.QtGui.so, 2): Library not loaded: /opt/local/Library/Frameworks/QtGui.framework/Versions/4/QtGui
Referenced from: /Volumes/NO NAME/dist/PyQt4.QtGui.so
Reason: image not found
When I look in dist, there is a file QtGui that is the same size as the one in /opt. So it seems the failure is dlopen(PyQt4.QtGui.so) returning a hard-coded path to the QtGui library. I'm guessing the solution is simple, but I haven't stumbled across it yet.
Update: I looked at the libraries in build/Contents/MacOS/PyQt4.*.so with otool, and these all have #executable_path (as opposed to hard-coded paths in dist). My stupid. So I repeated the process of moving the program, only using the MacOS folder rather than the dist folder, and executing macdise from the command line on my wife's MBP. The problem turned out to be in the way I was looking for the included_files. I changed this to:
if getattr(sys, 'frozen', False):
uiName = os.path.join(os.path.dirname(sys.executable), "tabDISE.ui" )
else:
uiName = "tabDISE.ui"
and it runs. What would have saved me a day would be a way to automagically dump the error message generated when executing from the command line to the console log. If someone knows how to do this, it would be a big help.
I've googled this error, that is received through both octave console and xoctave, and tried the suggestions to include the cd command followed by setting the IMAGE_PATH both to the same image path.
After trying the above suggestion, the imread still doesn't work emitting the same error; the path where the image exists is the very same as that of xoctave's default workspace. I've already went through Xoctave's options>console> Where is Octave to insert the correct directory to octave.exe and then saved and reopened xoctave.
The error is:
error: imread: cannot find image.jpg
error: called from:
error: C:\octave\3.2.4.gcc-4.4.O\share\octave\3.2.4\m\image\imread.m at 1ine 53, column 5
On octave installation, I've chosen the default installation settings (as partly seen below), as well as all the "Octave Forge" packages ("image" inclusive). I've then installed and extracted the image processing toolbox found here.
The strange thing is that I've had the same imread error on a different computer (running windows XP) that was resolved as soon as I've changed directory (cd) and set IMAGE_PATH to the required workspace. Also, on using ls to list the directory's contents, the image is found within as expected.
I'm using Octave 3.2.4 and Xoctave 0.9.79 beta; running on Windows 7 64-bit.
