Heroku Deployment Failed: OSError: libtorch_hip.so: cannot open shared object file: No such file or directory

Any ideas on why my app won't deploy? Build is succeeding -- deploy is failing.
Here are my requirements.txt.
-f https://download.pytorch.org/whl/torch_stable.html
Django==4.1.4
djangorestframework==3.14.0
requests==2.28.1
whisper==1.0
django-cors-headers==3.13.0
psycopg2==2.9.5
gunicorn==20.1.0
dj-database-url>=1.0,<2.0
whitenoise>=6.0,<7.0
torch==1.13.1+cpu
speechbrain
pyannote.audio
pyannote.core
I'm using torch==1.13.1+cpu because torch==1.13.1 causes the compressed slug size on Heroku to be >500MB, which isn't allowed.

AttributeError: function 'initGEOS_r' not found
I get AttributeError: function 'initGEOS_r' not found error while trying to run my server.
I am trying to write a basic Geo Django program
I have Postgres and GEOS also installed
I have also included GEOS and GDAL paths in my settings.py file.
I have tried all possible way to resolve this error but couldn't.
Can Someone Help me out!

I had the same problem this worked for me:
On settings.py write:
GDAL_LIBRARY_PATH = r'C:\OSGeo4W64\bin\gdal204'
GEOS_LIBRARY_PATH = r'C:\OSGeo4W64\bin\geos_c.dll'
PROJ_LIBRARY_PATH = r'C:\OSGeo4W64\share\proj'
On settings.py INSTALLED_APPS code:
'django.contrib.gis',
Add postgis to backend
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'xxx',
'USER': 'yyy',
'PASSWORD': 'xxx',
'HOST': '',
'PORT': '1234',
}
}
Remember that your models should inherit from
from django.contrib.gis.db import models
I hope this can help you

Same steps as the answer above, but on the M1 Macs, the settings looked like this:
GDAL_LIBRARY_PATH = "/opt/homebrew/lib/libgdal.dylib"
GEOS_LIBRARY_PATH = "/opt/homebrew/lib/libgeos_c.dylib"
(Didn't need PROJ because I'm using "ENGINE": "django.contrib.gis.db.backends.mysql",

Here is the question: an error occurs when I import pandas:
dateutil: No module named 'dateutil'
So i installed dateutil, which is successfully installed, with pip:
pip3 install python-dateutil

There are 2 line relating to my project, which use a biological packages, I don't know if that's the reason.
To continue my django project, i have to uninstall dateutil as a temporary solution.
How can I solve this problem?

This problem has been solved. It turns out I did not describe what the real problem is, it's pandas(0.25.3) conflict with django(2.2) instead of dateutil. I reinstalled a old version of pandas(0.24.1) and it can work. I don't know why, but it works. Hope this can give other people a hint when they have the same question.

anaconda3/bin/python: undefined symbol: archive_errno

I installed Anaconda 4.7.10 on Ubuntu 16.04.2 LTS and everything worked smoothly.
After a couple of days I wanted to install "sqlalchemy" but this time I got the error message below. Since then almost every conda command yields the message below. Includingconda update --all and conda upgrade.
Any suggestions?

I've came across the same error on my conda installation in windows subsystem for linux and could solve it by installing libarchive-dev. This seems to be some kind of hidden dependency, libarchive was not installed on my system previously.
apt-get install libarchive-dev
