synology NAS, pip issue, python libraries

I recently acquired a NAS and trying to run a python script. Issue is that I cannot run the python script as a normal user (python script.py). Python is only running if I run as a sudo user (e.g., sudo python script.py)
When I run as a normal user, it does not detect the libraries such as pandas. But I do not want to run as a sudo because sudo would required a password.
I think the issue comes from the pip installation.
Do you know what could be the issue?
Greatly appreciate
In the terminal, when I run "pip list" as a normal user, it states 'ModuleNotFoundError: No module named 'pip._internal'
`
user#NAS:~$ pip list
Traceback (most recent call last):
File "/bin/pip", line 5, in <module>
from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip._internal'
but when I run as a sudo:
user#NAS:~$ sudo pip list

You are using pip version 19.0.3, however version 20.2.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
Python that I chosen is 3.7.4
However, I need to executes the script, which it should be execute normally. However, I found that it caught error
Traceback (most recent call last):
File "d:\lib\runpy.py", line 193, in _run_module_as_main

File "d:\lib\runpy.py", line 85, in _run_code
exec(code, run_globals)
File "D:\Scripts\robot.exe\__main__.py", line 5, in <module>
ModuleNotFoundError: No module named 'robot'
that I don't understand that cause of error.
I have already got robot files as well

Have you found a solution yet? I doubt if your command to execute robot is correct.
robot <Path to robot file> will execute it.
for example robot Tests/my_robot_test.robot and if you have tags assigned, you can run specific tag test cases with robot -i <tag_id> Tests/my_robot_test.robot

When I do Flask run, it shows error : ModuleNotFoundError: No module named 'werkzeug.contrib'. Can anyone help me with this?

the exact error I get is :

I am trying to import sessions from Flask

Werkzeug 1.0.0 has removed deprecated code, including all of werkzeug.contrib. You should use alternative libraries for new projects. werkzeug.contrib.session was extracted to secure-cookie.
If an existing project you're using needs something from contrib, you'll need to downgrade to Werkzeug<1:
pip3 install Werkzeug<1

You will need to downgrade werkzeug version from 1.0.0 to 0.16.0
This solved the problem for me.
Just run the following commands in your project:
python3 -m pip uninstall werkzeug
and then
python3 -m pip install werkzeug==0.16.0

Either downgrade the version to 0.16.0 or replace werkzeug.contrib.cache with cachelib.
I can highly recommend upgrading the package. The deprecated module werkzeug.contrib is very easy to replace!
Install cachelib and replace all imports from:
from werkzeug.contrib.cache import FileSystemCache
to
from cachelib import FileSystemCache

If you still need deprecated code from werkzeug.contrib, you can downgrade Werkzeug version to less than 1.
pip install Werkzeug<1

For Python 3.8
python3 -m pip uninstall werkzeug
python3 -m pip install werkzeug
python3 -m pip install flask-session

After downgrading werkzeug:
pip install werkzeug==0.16.0
If you get the following:
flask 2.0.2 requires Werkzeug>=2.0, but you have werkzeug 0.16.0 which is incompatible
Consider doing:pip install flask==1.1.1

For my upgrade (0.15.5 -> 2.2.3) Everything is moved or removed from contrib to other modules. I recomend going to the documentation for your specific version of werkzeug and searching the library you are trying to import. I found mine!
from werkzeug.middleware.profiler import ProfilerMiddleware
app = ProfilerMiddleware(app)

Import of nltk version 3.2.3 fails with ImportError

I'm running python 2.7.13 under windows 10 and I'm struggling to get nltk properly running.
Here's what happens when I try to import nltk:
>>> import nltk
Traceback (most recent call last):
File "<pyshell#4>", line 2, in <module>

I have already tried to uninstall nltk and also uninstalled and reinstalled python and then I followed these instructions:
http://lizusefulstuff.blogspot.de/2012/03/how-to-install-nltk-package-for-python.html
However, with these instructions I get stuck with step 5. When I enter
python -m nltk.downloader
I get the message
C:\Python27\python.exe: No module named requests
Does anyone have a hint what I'm doing wrong here or what else I could try to get nltk running in my setup? I assume there is still a way to use nltk with python 2.7?
From what I found so far, it seems easier to install nltk with python 3.4 but I'd like to avoid a python upgrade, if possible, since aside from my nltk experiments I'm following along a coding tutorial that refers to python 2.7.
Thank you for any hints!

In the latest version of nltk (v3.2.3), there's an issue with "optional" dependency, see https://github.com/nltk/nltk/issues/1725
The ImportError would happen in any OS (Windows / Linux / Mac) since it's a python dependency issue.
This is due to the additional dependency that nltk.parse.corenlp needs but it isn't elegantly imported and the imports were exposed at the top level at https://github.com/nltk/nltk/blob/develop/nltk/parse/init.py#L81
To install nltk with requests to patch this problem:
pip install -U nltk[corenlp]
For fuzz-free installation, installs all packages that all nltk submodules would require:
pip install -U nltk[all]
Alternatively, you can install the request package separatedly:
pip install requests
Hopefully, issue #1725 gets resolved soon and a minor patched version of the release will be re-released soon.

Why do I get "ImportError: Twisted requires zope.interface 3.6.0 or later." when running stratum mining proxy?

The entire return when running "sudo python ./mining_proxy.py" is:
Traceback (most recent call last):
File "./mining_proxy.py", line 67, in <module>
from twisted.internet import reactor, defer
File "/Library/Python/2.7/site-packages/Twisted-13.2.0-py2.7-macosx-10.8-intel.egg/twisted/__init__.py", line 53, in <module>

raise ImportError(required + ".")
ImportError: Twisted requires zope.interface 3.6.0 or later.
This leads me to believe that zope.interface is not installed. So I try to install it:
sudo easy_install zope.interface
Searching for zope.interface
Best match: zope.interface 4.1.1
Processing zope.interface-4.1.1-py2.7-macosx-10.8-intel.egg
zope.interface 4.1.1 is already the active version in easy-install.pth
Using /Library/Python/2.7/site-packages/zope.interface-4.1.1-py2.7-macosx-10.8-intel.egg
Processing dependencies for zope.interface
Finished processing dependencies for zope.interface
I also find this post which says you basically need to put an init.py into the folder. So I do:
sudo touch /usr/local/lib/python2.7/site-packages/zope.interface-4.1.1/__init__.py
I try to run mining proxy again, same error. Please help.

I had the same error.
After googling around I found that the touch should be in a different place:
sudo touch /usr/local/lib/python2.7/site-packages/zope/__init__.py
however it didn't work.
I just fixed it using virtualenv
steps here:
pip install virtualenv virtualenvwrapper
mkvirtual stratum-proxy
pip install https://github.com/slush0/stratum-mining-proxy.git
pip install zope2
After those step inside the virtualenv stratum-proxy was working successfully.
hope it helps
