Django Tutorial (Database setup) Question

[Cai Gengyang]

Hello all !

So I am going through the (Database setup) chapter of this tutorial 
(https://docs.djangoproject.com/en/1.8/intro/tutorial01/) --- Its the section 
right after the first chapter on "Creating a project"

I opened up mysite/settings.py as per the instructions on the Django tutorial. 

However, when I try to run the following command : $ python manage.py migrate 
to create the tables in the database, 

CaiGengYangs-MacBook-Pro:Weiqi CaiGengYang$ python manage.py migrate  input 

I get the following error message : 

/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python:
 can't open file 'manage.py': [Errno 2] No such file or directory  output 

Any idea how to solve this issue? 

Thanks a lot !

Re: ConnectionError handling problem

[Gonzalo V]

Hi Cameron.
i had the same problems and you have to tell to python what to do with the
connect problem.
try this:

...
except *urllib.error.HTTPError* as e:
if e.getcode()==504:
disp = "SIN RESPUESTA DEL SERVIDOR" #(No answer from the
server)
nombre=''
origen=''

precioAhora=''
print(e.getcode(),disp)
pass


that works for me. You can handle any error. 404, and 500 and more. but you
have to tell him to python what to do.

greeting from Chile. Sorry my english.



Saludos,
Gonzalo

PY3.5 and nnumpy and scipy installation problem

[Ek Esawi]

Hi Steven,


Thank you for the prompt response. What I meant by not working is the
following: once I had py3.5 working, I downloaded numpy and scipy and
unzipped them. After that I tried to install them. But there is no install
file for either. There was a setup file which I thought would do the same.
However, when I double clicked it, it showed a python window for a sec and
that’s all.


When I went to IDEL and typed import numpy as np I got the following error
message which suggests PY did not find numpy.


>>> import numpy as np

Traceback (most recent call last):

  File "", line 1, in 

import numpy as np

ImportError: No module named 'numpy'

>>>



Thanks again, EK

Beginning question #compilersetup, #windows7, #vs2010

[Jeff VanderDoes]

All,

I'm fairly new to Python and was excited to start playing with it until I
ran into need to compile some extensions under windows 7 64 bit.  I've done
some searching but after more hours than I care to count being unsuccessful
setting up MS visual studio (2015, 2012, and 2010) with service packs and
SDKs I can tell I'm spinning my wheels and going nowhere fast.

After trying to search through archives and the net I get some things that
are really old or are unique to their situation but just not what I would
expect for such a widely used language.

Are there any instructions/pointers that someone could point me to to be
able to set up visual studio for use with python.  I figure I'd just start
with 3.5 but have tried under 3.4 and even went back to 2.7 with no luck.
I see I'm not the only one with frustration with the error about not find
vcvarsall.bat and the like.

Thanks for your help!

It worked for me ...

Step 1 : Download Python 3.5 from here --- https://www.python.org/downloads/
Step 2 : Install it 
Step 3 : Click on the 'IDLE' button --- for me , I am using a Mac so I click on 
'Finder', then type IDLE in the search field on the top right corner of the 
'Finder'. 
Step 4 : Click on the IDLE and it opens up, a happy looking 'Python 3.5.0' 
shell there. There is however a warning that this version may be unstable. 
However, I am able to execute commands on it like 1 + 2 = 3

Maybe if you told us the error (cut & paste it, don't retype it) we 
could help? Similarly knowing the OS you are using would help.


Without that info how can anyone help you?

What OS are you running under?
Just just typing python in the command window work?  What about
python3?

If they work, so you have a python

run 'python -m idlelib' in the command window.

This should give you an error message.  Paste it in here and
we will see what we can do.

The warning is about the Apple-supplied version of tcl/tk, not about 
Idle.  Any tkinter program could have a problem.

For 3.5 you should be able to just install Visual Studio 2015
Community Edition. This is the current release of Visual Studio, so if
you encounter problems, at least finding help won't be one of them.

2.7 is built with VS 2008, which is no longer supported. But, thanks
to Steve Dower, Microsoft distributes an unsupported version for
building Python 2.7 extension modules [1].

3.4 is built with the fairly old VS 2010, for which the free Express
edition is no longer available. But you should be able to configure a
command-line build environment. Install the Windows SDK 7.1 [2] and
the VC++ 2010 SP1 Compiler Update [3]. Then run the Windows SDK 7.1
Command Prompt [4], and enter

SetEnv /Release /x64

If you plan to do native debugging outside of Visual Studio, install
the Debugging Tools for Windows [5] when installing the SDK. You can
download public debug symbols for operating system components using
Microsoft's symbol server. To do this, create a "C:\Symbols"
directory, and set the following environment variable:


_NT_SYMBOL_PATH=symsrv*symsrv.dll*C:\Symbols*http://msdl.microsoft.com/download/symbols

Additionally you'll need Python's debug symbols, such as for 64-bit
3.4.3 [6]. I typically copy a PDB next to its related DLL/EXE. This is
what 3.5's installer does when you select the option to install debug
symbols (nice job, Steve!). You can also unzip the PDBs to a directory
that's in _NT_SYMBOL_PATH, or update the symbol path dynamically using
.sympath+ and .reload [7].

PY3.5 and nnumpy and scipy installation problem

[paul . anton . letnes]

Easiest way of installing is removing the python you've installed already and 
installing continuum's anaconda python 3.x (for x = 4 or 5). It has "batteries 
included" - numpy, scipy and many others!

I'll heartily recommend anaconda python. It's got everything you need

Remove what you installed before.

This code runs fine on physical FreeBSD/CentOS/Debian servers, Rasperberry PIs 
running
Raspbian, OSX, VirtualBox and VMware Workstation Linux servers, Windows  so 
I suspect
this is somehow VPS related but not sure where to start.

How are you expecting tkinter to work on a vps, when there is no window
system?  It wouldn't surprise me if tk is crashing.

Beside Paul's comment, I suggest running with 2.7.latest and tk

Also, Menubutton is considered obsolete for Window level menus, so it 
may not be maintained as well.  Just use Menu if at all possible.

I wonder if it's a missing or wrong .so since there's no X and maybe
no X libraries.  That might lead to a crash.

Perhaps there is nothing wrong with it. What makes you think that there is?

Do you get an exception? If so, the exception will tell you where to start:
read the error message, look at the line it says the error occurred at, and
fix the problem.

If you need help, COPY and PASTE the *entire* traceback, starting from the
line "Traceback (most recent call last)" to the error message at the end,
and send it to us.

Sure, I'll file a bug for you. So far, though, this is no different
from pretty much any tracker I know of, except that github's tracker
requires a github account as opposed to a
specific-to-the-python-tracker account.

What's the issue, precisely?

Presumably this, but I don't follow.

You may have heard about this thing called X Windows and this other thing called
ssh that easily permit VPS instances to run GUI code while displaying things
on a remote X server.


P.S. X applications like xterm work flawlessly on the hosts in question.

P.P.S.  You might want to dial down the snark, particularly since you seem
to be unfamiliar with the basics here.

Unfortunately, CentOS tracks the corresponding RHEL component versions pretty 
much exactly (that's sort of the
point).  Moreover, this exact OS release level works flawlessly in other kinds 
of VMs and physical instances.

I'd still be curious about the possibility of a missing/broken .so
file somewhere. On systems that don't have their own displays, stuff
can be missing or broken and nobody would notice. What happens if you
strace the thing? Are there any obvious issues with what it's loading
up?

The syntax looks fine in the pastebin, did you possibly copy text from

It could still be that tk requires some client libraries that are
missing, that xterm doesn't use.  xterm is a much older and cruftier
program.  Does Gnome work?  For that matter, does Idle work (it is
a tkinter client)?

I remember that a guy I used to work with ported tk to an embedded linux
box with a working X server and display, but still had a rather rough
time getting tk running.  All I can suggest is curling up with gdb for a
while.

This has a few diagnostic suggestions that seem worth a try:
http://ftp.ntua.gr/mirror/python/topics/tkinter/trouble.html

Next thing after that is probably curl up with gdb for a while.
