I am developing a website and want to put some files on the server. The problem is that I can only import python modules ( e.g. "import os"), but somewhy, can not import my own modules:
test1.py:
import test2
test2.py:
print ("Content-type:text/html\n\n")
print ("<html>")
print ("<head>")
print ("<title>Error</title>")
print ("</head>")
print ("<body>")
print (" hello world 2")
print ("</body>")
print ("</html>")
If I click www.mywebsite.com/test2.py, then I recieve "hello world" on the screen.
However, if I click www.mywebsite.com/test1.py, I get "500 internal server error." I found out that it is some problem with not being able to import my modules.
p.s. since I am on a shared server, I can not changes sys path etc....
Here is a trace I got in errors.log:

In the last line, you can see that the server writes "ImportError: No module named test2"
How can I fix it?
From your description, your program did not found your own module, because you did not give your module's path. Now there are two methods to solve it:
Assume your module's path is: /srv/modules/xxxx.py
First you should import your module in your program: import xxxx
command line:Before you run your program with command line, give the path first. command:
export PYTHONPATH=/srv/modules.Then run your program.
add two lines of codes in your program:
import sys
sys.path.append("/srv/modules")
Use any one way above, you should run your program success.I hope this can help you.
Modules should be in the Python path or in the same directory where the executable is.
Then you do like usually
import test2
test2.some_function() # or whatever.

As you can see the error is within the code of flask itself. I'm using Python-3.6.2 which is supported by flask. The source code of flask in which it's showing error is also correct. What could be the issue ?
Sorry for posting this rather then commenting:
Try to install Flask 1.1.1 which worked for me:
pip install Flask==1.1.1
I am getting below error when I start the httpd server and access the app url -

This started happening after my machine was replaced with new one. Previously app was working fine.
I found one reference to python2.7 in /etc/httpd/conf.d/wsgi.conf and that's what was causing the issue. After removing that, the app was up and running.. Thanks!
I try to configure mod_wsgi to access odoo thanks my domain name.
I followed this tutorial.

Your mod_wsgi is compiled for a different Python installation than the Python virtual environment you are trying to force it to use, or the Python shared library it is finding. Worse is that what ever it is using was compiled with different width for Unicode character support. You need to uninstall mod_wsgi and reinstall mod_wsgi from source code and compile it against the specific Python version you do want to use, forcing it to use the correct shared library if necessary. You may also want to consider reinstalling your custom Python version to use a configuration which aligns with what is generally regarded as best practice for the platform. Linux system usually use 4 byte Unicode, not 2.
Some stuff for you to read:
http://modwsgi.readthedocs.io/en/develop/user-guides/checking-your-installation.html#python-shared-library
http://blog.dscpl.com.au/2015/06/installing-custom-python-version-into.html
Ignore the fact that the latter talks about Docker, all still relevant to normal Python install as well.
I'm using apache with Flask and mod_wsgi.

How can I fixed this?
I suppose you are using a SELinux enabled distribution like CentOS. When your app is behind Apache using mod_wsgi, you have to set the label httpd_sys_script_exec_t to the shared object files before your app can access them.
In the following example I will assume that your application is in /var/www/myapp directory with Python 2.7 virtualenv in /var/www/myapp/venv and Numpy and Scipy is installed in that virtualenv as well.
You can add permanently the new SELinux policy using semanage:
semanage fcontext -a -t httpd_sys_script_exec_t "/var/www/myapp/venv/lib/python2.7/site-packages(/.*)?"
And then you can activate them with restorecon:
restorecon -R /var/www/myapp/venv/lib/python2.7/site-packages/
If you install a new package in the virtualenv which has a shared object file, then you have to run the restorecon command again (or reboot).
I am getting this in my error log file. Ive been searching for asolution but have found nothing. I am trying to deploy django with mod_wsgi.
