Re: [sage-support] Ubuntu 18.04 binaries for Sage 8.9?

[henri.gir...@gmail.com]

I tried sage conda is not really recent too and didn't work for me on ubuntu

The best is to compile it when possible

Are there any issues in creating these binary?

the only issue is the absence of a building host running Ubuntu 18.04
in our automatic binaries building system, run by a very small (about
1 person, I gather)
team of volunteers...
Just build it from source, it should be very easy, or use
an alternative package manager (e.g. conda, nix, etc...)

Re: [sage-support] Sage crashes on startup

[henri.gir...@gmail.com]

Ubuntu and sagemath are not really in phase... I am using 19.10 the 
coming one and I compile sagemath. But the good way too is to download 
the binary (latest one 8.9) and uncompressed it in your home you will 
have a sage repertory,


after you do a link  sudo  ln -s /your sage dir/sage /sage /usr/bin/sage

But you can use it at local too.

Hello,
I presume this is Sage installed as a standard Ubuntu 18.04 package, right?
What version of Sage is this?
https://packages.ubuntu.com/bionic/sagemath says it's 8.1
This is very old, no wonder it's broken.
The current stable Sage version is 8.9.

Hopefully people at sage-packaging (at cc:) could tell you a better
way to get a binary installation of Sage on Ubuntu 18.04 (or just
build it from source...)

So how can I save those pyc files generated by sage separately and

I think if you make your *.sage scripts more "pytonic", so that they 
can be imported by Python "import" statements, then it would suffice 
to supply *.pyc files only.


Thanks in advance

*.sage files are preparsed by sage preparser, and converted
into *.py files.
Conversion into *.pyc files is done automatically, as *.py
files are
loaded into Sage's Python interpreter.

One cannot load() or attach() *.pyc files, as far as I know -
but why
would you need this?
(unless you want to hide the source of your *.sage scripts
from the user)

Re: [sage-support] SageMath 8.7 crashed in WSL Ubuntu after installation

I guess he uses sudo to install the sagemath deb package as he is using

I am sorry for showing that. But now, I can use sagemath with this command in 
.bashrc
alias sage=''sudo ~/SageMath/sage'
I think this is because I use sagemath the first time with sudo. I don't know 
what happened during I running sagemath the first time.

This is because Sage maintains a data cache in ~/.sage/
Running Sage with sudo created/updated files in ~/.sage/ with wrong
(i.e. root) ownership,
It might have also changed ownerships of some files in
~/SageMath/local/ - although this is less likely.

You can see ownerships in ~/.sage/ by running "ls -alR  ~/.sage/", and
similarly for ~/SageMath/

You can (actually, you should) change ownerships back to your "normal" user
bu running "sudo chown -R ~/.sage/   "
and "sudo chown -R ~/Sage/  "
(where  should be replaced by your real username, -
something that on "real" Linux systems
is printed by the command "whoami")

This is assuming that "chown" actually works on WSL as it should...

Then it should not be necessary to use "sudo" any more.

Using "sudo" is a bad idea in such a case, e.g. as in Python you have
full access to the file system, so you can accidentally destroy your
WSL installation.

Let us know if all this makes sense and works.


Q2

and does it still work if you don't use the alias?

alias just replace the command. There is no different between alias the the 
original command.

Q3

Anyhow, we need a detailed bug report if you like us to look at it
("it crashed" is not enough - we need to see error messages, relevant
log files, etc)

I am sorry for my issue not so detailed. I use sagemath to do the experiment in 
my bachelor thesis. This PC for doing experiment still in the lab. I will come 
back to run the installation again and get the log file.

Thanks.

Hi Henri,

thanks for reporting. Note that, if you installed Ubuntu using
the Windows Subsystem for Linux, then as an alternative to

    apt install sagemath

which gives you SageMath 8.1, you could use the SageMath
binary for Ubuntu from the Sage download page at

http://www.sagemath.org/download-linux.html

(Choose a mirror close to you, then select 64-bit, then
download sage-8.7-Ubuntu_18.04-x86_64.tar.bz2
either using the torrent link, which should be the fastest,
or by clicking sage-8.7-Ubuntu_18.04-x86_64.tar.bz2.)

This way you get the latest version of Sage for the
Ubuntu you installed in the WSL.

Some have also reported success in compiling SageMath
from source in Ubuntu in WSL, so you could get the latest
development version, currently Sage 8.8.beta1.

Or apt.  I think too you should build it if you have enaugh system. You 
can install sagemath-8.1 from ubuntu so you get all dependencies, but 
that's not the best way, better use the link above. I use : sage -sh to 
install pip programms but don't forget to exit after... In ubuntu it's 
quiet easy to install all python and sage, but sage is a bit old 
sage-8.1 and personnally I have problems with this version, I would like 
to make my own deb but I didn't success yet.

sage -n=jupyter

Can you show your nice syntax hightliting from emacs ?

sagenb will not continue I do agree that the editor was better than in 
jupyter, but may be I don"t know how to use it properly ?


Nice books are done with jupyter notebook

Hi,

I used to use cocalc for my sage needs, but I would perfer using my 
own resources and run my stuff locally.


i found https://ask.sagemath.org/question/35772/error-on-display-latex/ .

is it correct that those are my only options to get graphical and 
nicely formatted output? i tried the twisted webserver (sage -n 
sagenb) and that was not so nice.


I do have nice syntax highliting etc in emacs, can i somehow get 
proper error messages and nicely formatted output with sage-shell-mode?

Re: [sage-support] Re: A case of immaculate conception...

[henri.gir...@gmail.com]

Hi John,

What is the difference between virginal conception and immaculate 
conception ?


I notice that sagemath can even cogitate in philosophy : Really a swiss 
knife ?


I don't believe in spontaneous generation ! lol

Apologies for the pedantry, but unless the indeterminates so generated 
are free of all bugs, then strictly speaking this is not immaculate 
conception; it is spontaneous generation, or perhaps virginal 
conception. ;-)

reset()

Id2=set(show_identifiers())
Id2 - Id1

which happily prints :

{'Id1', 'a', 'b', 'foo', 'p'}

Is this expected ?

Re: [sage-support] sage dev in /usr for ubuntu

[henri.gir...@gmail.com]

 Thanks, but I solve this by doing a link, I read the doc on 
debian.org, but it's too complicated for what I am doing... Once I have 
done ( https://github.com/aishenri/zip )


visualino_0.7.2-fr-_amd64.deb 
<https://github.com/aishenri/zip/blob/master/visualino_0.7.2-fr-_amd64.deb>


because I converted it in french, very easy, but it's not a real debian, 
no name of maintener, I only want to make sage deb for me to get the 
latest from my sources compilation. Sorry my english is not very good.

I can not understand your real question. What do you mean by
"make a deb"? You mean a Debian package? For that there is the
documentation on debian.org. Then I have no idea what do you mean
"this question about proprietary software".

Re: [sage-support] sage dev in /usr for ubuntu

[henri.gir...@gmail.com]

Thank you. I don't like to use /opt. My real question is how to make a 
deb without all this question about proprietary software. Ubuntu has 
sagemath 8.1 in path /usr/lib/sagemath, but sometimes I run my ipynb, by 
clicking on its name, and I thaught it would run sage-8.6 but therefore 
I need to create a link, that's what I will do and uninstall sagemath-8.1

Hi,

Unless your Linux distribution is very permissive you should never
access the /usr repo in write mode. The standard place to install
your custom softwares is /opt [1].

./configure --prefix=/usr make and make install if it could work ?
I have no risk on my pc if it's mess I just reinstall a fresh one.

installing librosa, and upgrade to get the last version)


Be careful to get out after installing software with exit, don't use it 
for something esle it will remain ou anyway...

How can I install Python packages into Sage using pip?

A google search reveals several posts suggesting to run sage -sh, then 
use pip install as usual. However, I get:


> pip is configured with locations that require TLS/SSL, however the 
ssl module in Python is not available.


And finally

> Could not fetch URL https://pypi.org/simple/zmq/: There was a 
problem confirming the ssl certificate: 
HTTPSConnectionPool(host='pypi.org', port=443):


Is there a solution?  I am using Sage on macOS (app version).
