Saving my IPython notebook fails.
I've set up a folder on a network drive which I'd like to save my notebooks to, but it isn't quite cooperating yet.
In ipython_notebook_config.py I've edited the following lines:
c.NotebookManager.notebook_dir = u'Z:\\Analytics\\Work\\MyFolder'
c.FileNotebookManager.notebook_dir = u'Z:\\Analytics\\Work\\MyFolder'
c.NotebookApp.notebook_dir = u'Z:\\Analytics\\Work\\MyFolder'
but still no joy.
This is IPython 2.1.0
I'm a little new to Python and IPython Notebook, so this may be obvious, not sure.
The following is the traceback:
Traceback (most recent call last):
File \"C:\\Anaconda\\lib\\site-packages\\IPython\\html\\base\\handlers.py\", line 286, in wrapper

os.mkdir(self.checkpoint_dir)\nWindowsError: [Error 5] Access is denied: u'.ipynb_checkpoints'
EDIT:
Thanks to Simon Smith below I tracked it down.
Checkpoints were still saving to the wrong place. I changed this line in the config:
c.FileNotebookManager.checkpoint_dir = r'Z:\Analytics\Work\MyFolder\.ipynb_checkpoints'
and now I'm sailing along. I've also edited the other paths to be r'such and such' as well. Thanks again.
The final line looks suspicious here:
os.mkdir(self.checkpoint_dir)\nWindowsError: [Error 5] Access is denied: u'.ipynb_checkpoints'
This looks like a permissions issue on that directory (i.e. ipython can't write any data to that location). There are instructions on how to change them here.

Im trying to run a python Server using CherryPy for a WebSite but when I run it this error pops up.
During handling of the above exception, another exception occurred:

It's my first time using this module and I don't know what's wrong.
I'm using Ubuntu 22, Python 3.10.6
Hard to say without seeing your exact code that this is calling.
Judging by the Error you are trying to use Sessions.
The sessions are looking for
/var/www/html/cncsessions
To place the session files in
But it gives an error. It looks like the path might be wrong. There's a double backslash at the end there and a forward slash.
\\/
If you haven't given up on this/figured it out already I would try changing this path to just this
/var/www/html/cncsessions
Also be sure you do not store your session data in your web root. Looks like from that path you might be doing that! Anything in a webroot will be served via public webserver. There's little to no chance anyone would guess the file names though.
I'v been trying to launch project(example_setup folder):
https://github.com/OTA-Insight/djangosaml2idp/tree/master/example_setup
I can anybody answer to men according with documentation. But it does not working. First problem, as I undesrtand is in date of methadata in SP(idp_metadata.xml)- validUntil="2020-12-27T12:41:18Z"> . It does not valid at the moment, and was changed to future date, as example(validUntil="2030-12-27T12:41:18Z"). But next I got another problem when trying to sign in to SP(localhost:8000) in my browser, I have more problem:

In attempts to find problem, I found the place where it is occured. In original it iis in tryexcept block, and can't be found easy.

My idp_metada in the SP is like in the [example_setup][1] folder of project, only validUntil has been changed as I said above, user in IDP has been created as superuser, I also tried to create user in the SP, the same as in the IDP, but nothing changed
Can anybody anser to me, what my problem is?
It's no any information in docs. But you need to create SP inside IDP from admin panel. That was resolved my problem.
I've a weird problem. I have coded a little python script to test if my idea would work (no worries, it's just for fun). I am trying to simply open visio, place a couple of objects and close it.
#Get visio application
import win32com.client as win32
visio = win32.gencache.EnsureDispatch('Visio.Application')
visio.Visible = True
And it worked, so I've left it as it is for this week and when I tested it again it gave me an error which didn't occur last time, and closed the application.

Does anybody know what happened, or what I'm doing wrong? I've tried to reverse an update that happened in the meantime. I've been looking if the win32com has been updated. Yet nothing did solve it.
I appreciate your assistance.
The awnser to this question has been posted here:
Why am I suddenly getting a no attribute 'CLSIDToPackageMap' error with win32com.client?
In short the problem can be solved by deleting the gen_py folder found in the temp folder. You can find the temp folder by searching for %temp% or go to c:\users<username>\appdata\local\temp (make sure to show hidden files).
Hope I was able to help.
I am trying to create an animated gig from a series of heat maps with HoloViews.
I need to do this in a Python script, i. e. specifically not in a Jupyter notebook.
When saving the image, Python throws an error because it cannot create a temporary file in the temp-folder of the current user (this is under Windows). Happens regardless of the user, even when I run Python as admin.
When I stop in the debugger and change the temp-file path to some other place, e. g. Desktop, that works, but the resulting holo.gif in the working directory is empty (0 bytes). The temporary gif, though, is correctly animated, so I guess the code is basically OK.
[Edit: Not so sure anymore. I ran this the night through on 26.531 heat maps each of which consisted of a 5x5 grid. The process did not finish (i. e. did not hit the breakppoint at Image.py line 1966). Is there a way to do what I want that is less painfully slow?]
Answers to similar problems on StackOverflow did point to permission problems (but what kind of problem could that be if it doesn't even work for an admin?) and suggest saving to another location, which is impossible here as I have no control over where matplotlib will try to create temporary files.
The problem is specifically with gif's, I can create *.png or *.html output without error. (AFAIK, the difference is that gif-creation uses ImageMagick.)
Here's the code (construction of underlying heat map data left out):
import holoviews as hv
hv.extension('matplotlib')
renderer = hv.renderer('matplotlib')
renderer.fps = 3
heatMapDict = {
k: hv.HeatMap(measurements[k].sensors) for k in range(len(measurements))
}
holo = hv.HoloMap(heatMapDict, kdims='index')
renderer.save(holo, 'holo', fmt='gif')
And the traceback:

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\y2046\\AppData\\Local\\Temp\\tmp4im5ozo8.gif'
Addendum:
I'm coming to think that this is not a permission problem after all. Perhaps it has to do with reentrancy and file-locking under Windows? The Python process in fact may create files in the temp directory, as proved by inserting the following test code before calling renderer.save():
import os
import builtins
filename = 'C:\\Users\\y2046\\AppData\\Local\\Temp\\test.txt'
fp = builtins.open(filename, "w+b")
try:
fp.write("first".encode('utf-8'))
finally:
fp.close()
os.remove(filename)
I should test this under Linux. If it works there, there must be a bug in the Pillow writer.
It looks like there is something broken with HoloViews. I have opened issue #3151 with them.
Yesterday I setup Apache to serve my Mercurial repositories and got everything working properly. I then tested pushing changes back to this repository and was presented with an error, and now that error pops up for every single operation I attempt - even just a simple GET request of the repositories! Here is the error:

My repository directory is owned by apache, the user running Apache. I dont know why './dev/fd' is being operated on either. I've restarted the server numerous times, recreated the repository directory, but I still get this error no matter what! I dont have access to restart the machine, so that is not an option. But it seems to have gotten in a very bad persistent state, and I dont know how to fix it. Any help is appreciated!
This turned out to be a configuration error on my part, and rather than delete the question I'll post the resolution here in case someone has this problem in the future.
Here was the hgweb.config I was using:
[paths]
/ = /var/hg/repos/*
#[web]
style = gitweb
allow_archive = bz2 gz zip
maxchanges = 200
allow_push = *
push_ssl = false
Two problems here, one is obvious. I had the [web] header commented out, and I assume that many of the options are not valid for the [paths] section. Also, after re-reading the Hg docs again, the push_ssl directive does not belong in the hgweb.config file, but rather in each repository's .hg/hgrc (or the ~/.hgrc of the user that runs apache). After fixing these, things are working perfectly!
