I have a DJANGO app. It is hosted on heroku. The site is working on the local server. I have made some changes to a django project. When deploying to heroku via github it fails.
The reason for the failure is below. But, I can't seem to work out how to fix it.
Please help with the fix:
File "/app/.heroku/python/lib/python3.9/site-packages/django/db/backends/utils.py", line 85, in _execute
return self.cursor.execute(sql, params)
psycopg2.errors.ForeignKeyViolation: insert or update on table "product_product" violates foreign key constraint "product_product_units_of_supply_id_47b2bb72_fk_list_supp"
DETAIL: Key (units_of_supply_id)=(6) is not present in table "list_supply_units".
The above exception was the direct cause of the following exception:

I want to fine-tune a pre-trained huggingface model for a particular domain. From this answer I know I can do it using run_mlm.py but I can't understan which format should I use for my text file. I tried to use a simple structure with one document per line and I get the following error:

I'm trying to run celery worker in OS X (Mavericks). I activated virtual environment (python 3.4) and tried to start Celery with this argument:
celery worker --app=scheduling -linfo
Where scheduling is my celery app.
But I ended up with this error: dbm.error: db type is dbm.gnu, but the module is not available

I switched to python3.5 and got the same error. On Ubuntu I could fix it with
aptitude install python3.5-gdbm
I got the same error. On Macbook I could fix it with
brew install gdb
I tried to load list of AWS images using Python boto library. So my code is like
con = boto.connect_ec2(user, pasw)
con.get_all_instances()
con.get_all_images()
Problem is that, get_all_instances() works fine, but get_all_images() is not responding. When stop application from kbd, I see

It seems like Boto's function is not working, AWS API is not responding. Have anyone similar problem? Thanks.
Reason was that the get_all_images function returns all images from AWS, so it works about few minutes. I started to user filters and now it takes reasonably time.
background
So I have a Pyramis app with a whole lot of models that relate to each other in different ways. These models were initially kept in a bunch of different files according to their general roles. For example I had a file called auth_models.py that contained the definition for User and Group.
I've been battling to deal with imports and suchlike because all the model files relate to each other in such a complex way so I gave in and placed all of them in the same file. And then I updated all my import statements elsewhere so everything should work.
Now whenever I try to access any view at all I get an internal server error. It turns out that the error is caused by the fact that auth_models.py no longer exists. The error is coming from a picklie.loads statement so I figure there is some session info being loaded that is no longer working. The full error message as well as my session settings are included at the end of this question.
question
If my assumption is correct, how would I get Pyramid to 'forget' the last sessions in a safe way?
If my assumption is incorrect, what's the best way to fix this? I don't want to revert to my old directory structure because that causes it's own problems...

ImportError: No module named 'pyramidapp.models.auth_models'
You have stored some of your model instances in a session cookie, which uses pickle to serialize and deserialize that data.
Because you moved the model to another module, pickle can no longer load the session data.
You can do two things:
If you don't care about the session data, simply delete your session cookie. Use your browser tools to delete the cookie manually, perhaps delete all cookies for your site.
Create an alias for the model in the old location. Create a pyramidapp.models.auth_models module that simply imports the models that used to be there. This module does not need to be imported by anything else, pickle will load it for you when needed.
Any future sessions will be created with the new location of your models, this affects only old session data.
