When I run this script "python3 script.py" everything is alright.
(I tried to run the script as a root, and other user too)
import music21
import os
# "qt.qpa.xcb: could not connect to display"
# "qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found."
os.putenv("QT_QPA_PLATFORM", "offscreen") #handle error above in my case
us = music21.environment.UserSettings()
us['musescoreDirectPNGPath'] = '/usr/bin/musescore3'
score = music21.converter.parse("myfile.musicxml")
score.write('musicxml.pdf', fp='song.pdf')
But when my django backend has to execute this code as a function to respond API call, its not working. I got:
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-myusername'
This plugin does not support propagateSizeHints()
And if I remove part with "QT_QPA_PLATFORM", I got "qt.qpa.xcb" error.
I have not idea what to do.
I also tried to add following line in my gunicorn setup script but nothing changed.
export QT_QPA_PLATFORM=offscreen
Any ideas how to fix it ? What can be wrong ?
Server OS: Ubuntu 20.04
You probably need to also set XDG_RUNTIME_DIR. See https://github.com/cuthbertLab/music21/issues/260#issuecomment-834489173

I am trying to simply upgrade the version of vue3 we are running at work from v3.2.31 to v3.2.40. However, when I do, I am now getting an error in the runtime-dom.d.ts
Below is a screen shot from the file with vue v3.2.31 installed.
Once I've run the "npm update vue --save" command, the file looks like this (v3.2.40)...
...and VS 2022 throws the following error when trying to build...
If I delete the line from my local copy of runtime-dom.d.ts, all works as before. My problem comes when deploying the solution to the development environment etc. The npm install step puts a version of the runtime-dom.d.ts that does still have this line.
I'd like to fix this without having to resort to hacking the runtime-dom.d.ts file if at all possible.
Many thanks in advance.
I'm trying to run my first deno script which is pretty much from the denoDB docs, it just tries to connect to a database with a SQLite3 connector (I'm on a Macbook pro so it should be installed):
import { Database, SQLite3Connector } from 'https://deno.land/x/denodb/mod.ts';
const connector = new SQLite3Connector({
filepath: './db.sqlite',
});
export const db = new Database(connector);
I'm running deno run api/db.ts and I get this error after a few successful downloads:
Download https://deno.land/std#0.149.0/encoding/hex.ts
Download https://deno.land/std#0.149.0/hash/_wasm/lib/deno_hash.generated.mjs
error: Import 'https://dev.jspm.io/inherits#2.0' failed: 500 Internal Server Error
at https://raw.githubusercontent.com/Zhomart/dex/930253915093e1e08d48ec0409b4aee800d8bd0c/lib-dyn/deps.ts:4:26
I've deleted my /Users/<me>/Library/Caches/deno/deps/https and reran the script a few times but I still can't get past this. In my browser trying to follow the URL https://dev.jspm.io/inherits#2.0 does give me an error. What is going on here? There's not much code and I imagine it's not broken for everybody. What do I need to do to get this script to run without issues?
EDIT: it seems to be a library error https://github.com/eveningkid/denodb/issues/348
This is an error caused by a nested depedency, from a project that is not maintained.
See this for more info: [https://jspm.org/jspm-dev-release]
The point is dev.jspm.io is now jspm.dev
A way to fix this is to fork and update depedencies.
Another thing, if you're not using deno deploy, you can just use this as a replacement for your denodb: https://raw.githubusercontent.com/joeldesante/denodb/master/mod.ts
Just note that this script is no more maintained either, but it will fix your problem
Edit
I just made a dirty quick fix for deno deploy use this as a depedency isntead of denodb: https://raw.githubusercontent.com/ninjinskii/denodb/master/mod.ts
Again, i may not maintain this script forever.
The best thing that can happen is an update from these libs maintainers
Hello I'm trying to do web scraping with the python module requests-html to handle dynamic content on the page https://www.monster.com/jobs/search?q=Software+Engineer&where=. My code is:
from requests_html import HTMLSession
url = 'https://www.monster.com/jobs/search?q=Software+Engineer&where='
session = HTMLSession()
response = session.get(url)
response.html.render()
but when I run response.html.render() I get this error
OSError: [WinError 14001] The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail
The first time I ran render() I got
[W:pyppeteer.chromium_downloader] start chromium download.
Download may take a few minutes.
[W:pyppeteer.chromium_downloader]
chromium download done.
[W:pyppeteer.chromium_downloader] chromium extracted to: C:\Users\user\AppData\Local\pyppeteer\pyppeteer\local-chromium\588429
however the file path doesn't exist but pyppeteer is actually an installed package (pyppeteer==0.2.5). Does anyone have an idea what is going on?
You're having this issue because chromium setup failed.
You can either try to reinstall request_html or what I did was switching from the python from the Windows store to the download from the python website and then installing request_html again.
After having everything setup correctly with the downloaded python I switched back to python 3.9 from the store and everything is still working.
I have a TVML app working quite nicely now in the simulator. I've started with a menuBar template, and have used a stackTemplate as well as productTemplate. Everything is working just dandy in the simulator. However, when I hook my Apple TV up and try to run it on there, the application loads, but then I get the following error:
TVMLKitErrorDomain error 3
I have been trying to find out what this is for a few days , but I have not found any information pertaining to the error code. The simulator version is running on the localhost 9001 like Apple recommends and that is flawless. I just can't get the app to run properly on the device though. Does anyone know what that error is, and how I can fix it? As always I appreciate your help!
You need to run this command from the same directory as your TVMLKit JS file:
python -m SimpleHTTPServer 9001
.
I had same error in my TV app. Solved by editing Info.plist. This error indicates that URL user trying to visit is not reachable.
You need to allow http:// from Info.plist for your app.
If you are running on device, you should change this line from localhost to your IP address:
static let TVBaseURL = "http://localhost:9001/"
to
static let TVBaseURL = "http://MY.IP.ADDRESS.HERE:9001/"
Just open a new terminal at your app folder and run the following command before running the simulator:
ruby -run -ehttpd . -p9001
I already installed OpenCPU on a Ubuntu Server - Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-32-generic x86_64) - and everything worked perfectly without any problems.
Here I want to say that I really like this API and I am very thankful for all the effort from the people (I think mostly Jeroen Ooms) working on it.
Now I installed it again, but on another Server hosted at another provider. It is also a Ubuntu Server - Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-042stab093.4 x86_64) - and therefore I expected it to work as smoothly as before.
But now I have a problem. After the installation and starting the service, I wanted to check through my browser if everything is OK.
So I just opened http://xxx.xxx.xxx.xxx/ocpu like it worked on my other server. This time my browser doesn't show the OpenCPU API Explorer, but the following message:
Failed to set rlimit. ENOSYS
In call:
rlimit_wrapper("rlimit_as", hardlim, softlim, pid, verbose)
The server only has 1GB of physical memory, so I thought changing the "rlimit.as" to 1e9 instead of the standrd 2e9 would fix the problem (I also tried 750000000 and 500000000), but nothing helped (of course I restarted the service opencpu again after each change).
I also think that this is not the problem, because I guess the server would use virtual memory when an operation uses more than one GB.
I think the problem has to do with RAppArmor. So I tried to disable it and restart opencpu, but the problem didn't vanish:
$ sudo aa-disable usr.bin.r
Disabling /etc/apparmor.d/usr.bin.r.
Traceback (most recent call last):
File "/usr/sbin/aa-disable", line 30, in
tool.cmd_disable()
File "/usr/lib/python3/dist-packages/apparmor/tools.py", line 148, in cmd_disable
raise apparmor.AppArmorException(cmd_info[1])
apparmor.common.AppArmorException: 'Warning: unable to find a suitable fs in /proc/mounts, is it mounted?\nUse --subdomainfs to override.\n'
So does anyone know what the problem here could be or has any suggestions where to look for a solution (I tried to google already, but didn't find anything helpful)?
I don't think anything of the following is the cause of the problem, but since I'm not sure, I add these warnings anyways:
The only strange thing I encountered during the OpenCPU installation was this message (which appeared 4 times):
iptables v1.4.21: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
But afterwards it said:
* Reloading nginx configuration nginx [ OK ]
OK
Setting up opencpu (1.4.4-trusty15) ...
Also when I tried to install RAppArmor separately, I got the following warning:
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LANG = (unset)
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
Selecting previously unselected package r-cran-rapparmor.
And also this one:
Warning: unable to find a suitable fs in /proc/mounts, is it mounted?\nUse --subdomainfs to override.\n
Thanks in advance!
It looks like your new hosting provider uses some sort of virtualization system that has a shared kernel which limits all kind of linux functionality, including rlimit, iptables and probably apparmor. Is an actual cloud host, or something you setup yourself?
It would be helpful to debug this in R (outside of opencpu). On your server, start R in the console and type:
library(RAppArmor, lib="/usr/lib/opencpu/library")
rlimit_as(1e9)
rlimit_fsize(1e9)
rlimit_cpu(1e5)
