Pyp3 gives ModuleNotFoundError even if packaged is install

So I'm trying to figure out if I can speed up my code. For that purpose I installed pyp3. But when I try to run the python file using pyp3 I get error in the first line itself ModuleNotFoundError, But when I use simple python my code works smoothly. Is it due to python version difference ? I'm new to pyp3. Any suggestion/help would be appreciated. Thankyou

twisted module not found error from Python Flasky

I am having trouble in running a flask file that is manager.py on Windows 10. Although I installed requirements, it still aborts an import error.What's funny is the errors are different in PyCharm and cmd. And I activated the same virtual environment.I will appreciate it if someone can help me!
In PyCharm:
Traceback (most recent call last):
File "C:/Users/Administrator/Desktop/Online-serial-debugging/manage.py", line 6, in <module>
from app import create_app
File "C:\Users\Administrator\Desktop\Online-serial-debugging\app\__init__.py", line 2, in <module>
from flask.ext.twisted import twisted
File "C:\Users\Administrator\Desktop\online\Online-serial-debugging\enve\lib\site-packages\flask\exthook.py", line 87, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.twisted.twisted
Process finished with exit code 1
In CMD:
(enve) C:\Users\Administrator\Desktop\online\Online-serial-debugging>python manage.py
Traceback (most recent call last):
File "manage.py", line 5, in <module>
from flask.ext.script import Manager
ImportError: No module named flask.ext.script
Here are my requirments.txt:
construct==2.5.2
dominate==2.1.16
Flask==0.10.1
Flask-Bootstrap==3.3.5.3
Flask-Moment==0.5.0
Flask-Twisted==0.1.1
Flask-Script==2.0.5
itsdangerous==0.24
Jinja2==2.7.3
MarkupSafe==0.23
observable==0.1.0
pyserial==2.7
six==1.10.0
Twisted==15.4.0
txsockjs==1.2.2
pypiwin32
Werkzeug==0.10.4
zope.interface==4.1.2

Please fix your import statement as follows, and could you try?
from flask_script import Manager
EDIT
Sorry, even using flask.ext.{}, it seems still works.
If you run the following command, what come back?
pip install Flask-Script==2.0.5

It means that 'Flask-Script' was not installed, check your 'pip freeze'.
Was there any error when installing the requirements? If so, try to identify the issue.
Try installing it:
$ pip install Flask-Script

OK. The problem is solved.orz. My command line is :
python manage.py
Actually, I used the Python interpreter in system path by mistake.And I run this command :
./enve/Scripts/python.exe manage.py
There are no import errors again, thank you who answered me still.

sompy Module Import Error

I can't import the sompy module even though I installed it successfully, and it appears in the modules list of my python environment:
When I try to import the sompy module using the following statement:
import sompy
I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'sompy'
What's wrong?

Which interpreter/IDE are you using? If using PyCharm, the problem could be that PyCharm hasn't identified a root folder for your .py project.
I would try and recreate the root folder as a subfolder and right click > Make source directory.

GDB pretty printing ImportError: No module named 'printers'

I'm trying to add pretty printing for STL in my GDB on Ubuntu 14.04. Some details on the tools:
OS: Ubuntu 14.04
gdb version: 7.7
python version: 2.7.6
python3 version: 3.4.0
But after I setup exactly as what the instruction said. I still get the following errors:
Traceback (most recent call last):
File "<string>", line 3, in <module>
File "/home/jerry/myLib/gdb_stl_support/python/libstdcxx/v6/__init__.py", line 19, in <module>
from printers import register_libstdcxx_printers
ImportError: No module named 'printers'
/home/jerry/.gdbinit:6: Error in sourced command file:
Error while executing Python code.
Reading symbols from main...done.
Then I haved double checked my pretty printing installation directory. Under the directory /home/jerry/myLib/gdb_stl_support/python/libstdcxx/v6/, I can clearly see I have the printers.py file. And I also view the content of printers.py, I'm sure it also has the register_libstdcxx_printers class. Why the python interpreter is still complaining the printers module is missing? This seems really strange to me.

I just tried something myself, and luckily, now it's working. At least it can print out the map and vector content as expected. Here is what I did:
Since it's complaining that it can't find the printer.py module, then I think should probably I tell python interpreter where this file is located. So I first added this extra line to my ~/.gdbinit:
sys.path.append("/home/jerry/myLib/gdb_stl_support/python/libstdcxx/v6")
(After the line sys.path.insert(0, '/home/jerry/myLib/gdb_stl_support/python') )
Then running gdb again, I got the following error:
Traceback (most recent call last):
File "<string>", line 5, in <module>
File "/home/jerry/myLib/gdb_stl_support/python/libstdcxx/v6/printers.py", line 1247, in register_libstdcxx_printers
gdb.printing.register_pretty_printer(obj, libstdcxx_printer)
File "/usr/share/gdb/python/gdb/printing.py", line 146, in register_pretty_printer
printer.name)
RuntimeError: pretty-printer already registered: libstdc++-v6
/home/jerry/.gdbinit:7: Error in sourced command file:
Error while executing Python code.
Given the error information, I edited the ~/.gdbinit file and commented the line register_libstdcxx_printers (None).
And then after running gdb, it works.
But I'm still wondering if directory in sys.path is searched recursively? I mean in my mind, the python interpreter should work like this: once you have added one directory to sys.path, then the subdirectory under that directory will also get searched for a module file.

Python import module using command prompt

I have a code in Python 2.7 write using the IDLE PyCharm on Windows 7 OS. Running inside the IDLE i have no problem to import all modules. When i run with the command prompt of windows i get this error message:
C:\Users\samsung>C:\PythonScript\TOOL.py
Traceback (most recent call last):
File "C:\PythonScript\TOOL.py", line 5, in <module
>
import ogr
ImportError: No module named ogr
I can import this module with the IDLE without problem.
