I'm trying to deploy a simple CRUD Django app suing the service of render.com. I have set up the config based on their documentation, but when I try to deploy it, the error ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt' comes up.

Launched Data Science Python 3 instance in the SageMaker Studio.
Launched a terminal from the Notebook menu "Launch terminal in current SageMaker image".
Tried to run pip but it says not found. Do I need to install pip by myself?
root#datascience-1-0-ml-t3-medium-1abf3407f667f989be9d86559395:~/# pip

Alto there is no Python3 available apparently from within the terminal.

And can run pip in the cell.
Appreciate any explanation what is going on.
SageMaker Studio image terminals use conda for package management. The data science notebook uses the base environment. You can use pip once you switch to base (also note that the python version is 3.7).

I work at AWS and my opinions are my own.
Was stuck in the same issue in Sagemaker notebook instance. Followed the guide here and resolved it by running:
%pip install matplotlib
Attaching the screenshot for your reference:
I just started to use uWSGI and Django. I want to invoke it manually.
I'm using python36, Django 2 and if I install uWSGI (pip install uwsgi) in venv and everything is ok.
Q1. When using outside of venv I first installed uWSGI:
pip install uwsgi -> 2.0.18 version
Installed plugins: sudo apt-get install python3-setuptools
Trying to run with python36:
uwsgi --plugin-dir=/usr/lib/uwsgi/plugins --plugin python3 --master --http :5000 --home ~/my_playground/webapps/ --chdir ~/my_playground/webapps/p_tscze/ --module p_tscze.wsgi:application
Plugins in /usr/lib/uwsgi/plugins:
/usr/lib/uwsgi/plugins$ ls | grep python3
asyncio_python36_plugin.so
asyncio_python3_plugin.so
python36_plugin.so
python3_plugin.so
Result obtained -> note python 2.7:
!!! UNABLE to load uWSGI plugin: ./python36_plugin.so: undefined symbol: uwsgi_legion_scrolls !!!

So please can you let me know what I'm doing wrong?
Q2. When comparing the result of the admin page (./manage.py runserver) and result obtained using uwsgi frontend is not the same, why?
Thanks in advance

Running the django tutorial for docker compose, but the command to init the django project is not working as expected.
$ docker-compose run web django-admin.py startproject composeexample .

Please pass the -d flag when using `docker-compose run`.
In windows "interactive" mode is not supported so I modified the command to run in "detached" mode.

This seems to create the boxes.. but my current directory shows no new files (from the django-admin command).
$ ls

How do I get the container output to sync with the current working directory as expected?
The fix was to uninstall Windows 10 and install a *nix system. The files then appear as per the tutorial.

I am having a an issue where I can't get uwsgi to run on my machine. I keep getting this:
/usr/bin$ sudo service ppuwsgi start
>>ppuwsgi start/running, process 17452
/usr/bin$ sudo service ppuwsgi status
>>ppuwsgi stop/waiting
I think I might be having a similar issue as this guy here. However, I didn't install from source. I saw that the machine came with python3.4. But I did do
sudo apt-get install libpq-dev python3-dev
and maybe even
sudo apt-get install python-dev
I want to think I don't have python installed twice. And I have no idea how to check and see. I opened up my usr/local/bin and saw uwsgi and some pip stuff but no python.
Lastly, here is my /etc/init/ppuwsgi.conf
# file: /etc/init/ppuwsgi.conf
description "uWSGI server for PingPlot"
start on runlevel [2345]
stop on runlevel [!2345]

The sock file and log file seem to get created as well (the log file is empty). I don't know what the deal is.
Edit:
So I opened up user/bin/ and here are all the python things I have.
EDIT: I LIED
I am getting stuff in the error log. I just couldn't see it because I opened vim without sudo. Here is the error log:

Based on the error log. I changed my version of Python. I uninstalled uwsgi and pip and then reinstalled it using python3 pip.
sudo apt-get install python3-pip
sudo pip install uwsgi
Then I was able to get uwsgi running.
That have:
1) ubuntu 11.10
2) cherokee (https://launchpad.net/~cherokee-webserver/+archive/ppa) (version 1.2.101)
installed like this:
sudo apt-get install cherokee
sudo apt-get install libcherokee-mod-rrd
sudo apt-get install cherokee-doc
3) uwsgi (version 0.9.8.1-1)
installed like this:
sudo apt-get install uwsgi uwsgi-plugin-python
4) Django 1.3.1 (sudo pip install django)
Run:
1) add example.com to hosts file (example.com 127.0.0.1)
2) create uwsgi.xml
<uwsgi>
<pythonpath>/var/www/vtest/</pythonpath>
<pythonpath>/var/www/</pythonpath>
<app mountpoint="/">
<script>django_wsgi</script>
</app>
</uwsgi>
and django_wsgi.py
import os
import django.core.handlers.wsgi
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
application = django.core.handlers.wsgi.WSGIHandler()
3)
/var/www$ sudo django-admin.py startproject vtest
/var/www$ sudo chown -R www-data:www-data vtest/
Move file uwsgi.xml, django_wsgi.py to /var/www/vtest and chmod +x django_wsgi.py
4) add virtual server in cherokee-admin vservers -> add -> platforms -> uwsgi choise uwsgi.xml document root /var/www/vtest
in console:
ps -A | grep uwsgi
