I have a database that is being used by my django project and a php project. So now i am about to add another separate django project which will use the same database.
After setting up the project i wrote models.py and when i tried to run server it is giving error: -

How to cope up with this type of problem.
Make you models and create migrations.
After this run fake initial migration

So, I am trying to install, and run Mujoco-py on my ubuntu. Everything went well but, I cant install the libglew1.5. I searche for it in the Ubuntu Package Archives, but no luck. Then I skipped that part, but when im trying to run the example its giving me this error.

I'm trying to revive an undocumented python server at work and I'm running into an issue with a missing file. When attempting to connect to the SQL DB with the credentials I've provided, I run into the following error:

MySQLdb._exceptions.OperationalError: (2059, 'Plugin http could not be loaded: /usr/lib/mysql/plugin/http.so: cannot open shared object file: No such file or directory')
Sure enough, there is no http.so file at that location, though there is a healthy bunch of others. I cannot find any documentation on why this may be or where I'm supposed to get it.
I'm using Arch Linux, and just installed from the AUR using sudo pacman -S mysql. This is just an alias for mariadb from what I can tell, but I don't think that's an issue.
Is this shared object something I can get somewhere? Not sure really what to do here.
Came across a thread for HeidiSQL, which from what I read is a MySQL admin tool of sorts. Anyways, a user had the same issue over there, and someone responded with this:
Just don't use any protocol prefix in the hostname, unless you know it's required and correct. In most cases there must be just the hostname or an ip address, without a protocol.
https://www.heidisql.com/forum.php?t=27104#p34471
Sure enough, I was using http:// in my hostname. Removing that works just fine, though isn't so much of a solution as a workaround.
We are using Powerpoint and Restructured Text together with Python-Sphinx. I was asking myself, if it is possible to create slides using ReST.
I found the interesting Tool rst2html5slides on
https://rst2html5slides.readthedocs.io/en/latest/index.html.
I installed the tool with:
pip install rst2html5slides
This worked without problems.
Now, I was unable to use the tool. Typing rst2html5slides on my console gives:

What I'm doing wrong here?
rst2html5slides' author here. I've updated the package a while ago. Please, update it and it should run.
I want Pyramid, Python3, SQLAlchemy and MySQL to play nice on a single machine. This question has been asked before, but it was a long enough time ago that I'm hoping the answer has changed...
Questions:
What driver works for getting a Python 3 Pyramid app to talk nicely to MySQL via SQLAalchemy? Is this even possible?
I've gotten quite far in this project thinking it would be a simple thing to switch out databases, now I'm a bit stuck and downgrading to Python 2.7 is not something I want to have to go through. So my second question is:
If there is no way to talk to MySQL nicely without downgrading, is there a database that Python 3 is ready for (besides SQLite)?
Or lastly, how would I overcome any of the problems mentioned in the 'Stuff I've Tried' section below?
Stuff I've Tried:
PyMySQL
I have PyMySQL installed and I even got it to complain about incorrect passwords and a missing database so it's getting something right. But when I tried to initialize my database (using initialize_foo_db) everything went sour:

oursql
I tried installing oursql using pip install -r file
where file contains:
#oursql==0.9.3 but need special Python 3 build https://bugs.launchpad.net/oursql/+bug/1051512
https://launchpad.net/oursql/py3k/py3k-0.9.3/+download/oursql-0.9.3.zip
pyramid==1.3.4
And I got:
oursqlx/compat.h:13:19: fatal error: mysql.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1
myconnpy
This installs without error but I can't seem to find out what I should tell SQLAlchemy to look for. In the appropriate settings.ini file I have tried:
sqlalchemy.url = mysql+myconnpy://...
as well as a bunch of other things. Google is failing me on this one...
UPDATE - a semblance of progress
I've managed to install oursql build dependencies:
sudo aptitude install python-pip libmysqlclient-dev
I then downloaded oursql0.9.3 and ran:
setup.py install
The output was this:
cython not found, using previously-cython'd .c file.
running install

running install_lib

running install_egg_info
Writing /path/to/virtualenv/foo/lib/python3.2/site-packages/oursql-0.9.3.egg-info
I opened a shell and apparently the module doesn't exist - it can't be imported anyway. But for some reason it is listed if I say help() then modules
I'm having trouble getting SQLAlchemy to work with my compiled app after getting through py2app. I've done this successfully in Windows with py2exe. The following is my setup file:
APP = ['Blah.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True,
'includes': ['sip',
'PyQt4._qt',
'sqlalchemy.dialects.mysql',
'MySQLdb',
"gzip"]
}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
This appears like it's the right way to do it, as I've seen people use it for sqlite, however I still get this error upon trying to run the app after compile:
sqlalchemy.exc.ArgumentError: Could not determine dialect for 'mysql+mysqldb'
I've recently been trying with PyInstaller and have gotten stuck at pretty much the same spot, albeit with a different error which is the following:

you probably also need _mysql which should include the native mysql bindings. also, this bindings need the binary mysql libraries to be installed on the target system.
your application would probably be a lot more portable if you used a pure python mysql library, such as pymysql or MySQL Connector/Python (both are supported by sqlalchemy)
