I am trying to make a portable application from a python app I developped on Windows 7 - 32 bits using python3.4. My first idea was to use py2exe combined with a ThinApp equivalent, but as I use rasterio which is not a pure python library, py2exe does not manage to find some DLLs.
If I try to run the generated executable I get this error :
File Traceback (most recent call last):
File "viewer.py", line 3, in <module>
import MainWindow as GUI
File "C:\Users\IEUser\Documents\viewer-dev\viewer\MainWindow.py", line 2, in <module>

File "<loader>", line 8, in __load
ImportError: (DLL load failed: The specified module could not be found.) 'C:\\Users\\IEUser\\Documents\\viewer-dev\\dist\\rasterio._base.pyd'
I read that I had to add these DLLs manually in the dist directory, but I wonder how could I get a list of the required DLLs ?
You can use the Dependency Walker on your py2exe to see all the missing dependencies.
Check the executable and all the linked libraries(PYD & DLL files)

Please let me know the solution to fix it as didn't find much on google.

I always launch Jupyter Notebooks from either from the Windows menu or the Anaconda Navigator. Almost always from the Windows Start Menu.
When I installed Anaconda a shortcut was created within the Start Menu, and when clicked it launches a cmd window, runs some scripts and then opens the Jupyter Explorer page within my default browser.

Issues with pyinstaller and pyproj
(3 answers)
Closed 2 years ago.
My code works well when it's .py
but when I make .exe file with pyinstaller, it shows ModuleNotFoundError.
I write this when I made .exe
pyinstaller -F MyCode.py
How can I solve this problem?
I've read
Issues with pyinstaller and pyproj
and I was going to try to make and located hook-pyproj.py at "hooks" folder in Pyinstaller. but hook-pyproj.py was already there with the same code.
After that, I installed "basemap" and tried to use pyproj from it. However it shows me the same error.
This is the error it showed me when I execute the .exe file.
(I covered some information with *****)

This is my code.
from mpl_toolkits.basemap import pyproj as pyproj
I tried this at first.
import pyproj
but I get same " ModuleNotFoundError: No module named 'pyproj._datadir' " error.
It's a bit odd and I don't exactly understand why but I found a quick dirty fix.
You can add this import
from pyproj import _datadir, datadir
to your existing one.
I noticed this pyproj import dll error error occurred on some Windows machines and not others.
Turned out to be a dependency on Visual C Runtime 2015+

When I try to run CADRE plug-in it fails when trying to import 'MBI' module in 'CADRE.power' discipline:
Traceback (most recent call last):
File "C:\Users\Laurynas\CADRE\src\mppt.py", line 9, in <module>

from MBI import MBI
ModuleNotFoundError: No module named 'MBI'
Is this some kind of legacy python or OpenMDAO module? I was not able to find it in the web.
Yeah, MBI is a separate package, but you can find it here:

I am using the Anaconda environment for python.
I have installed the paramiko (v. 2.0.2) and cryptography (v 1.5) modules using the Anaconda Navigator..
When I try to execute this import statement:
import netmiko
I get an error message "ImportError: No module named cryptography.hazmat.backends"
The total output in the cmd window is:
>>> import netmiko

ImportError: No module named cryptography.hazmat.backends
Does anyone know how to fix this?
Any help is appreciated.
I guess the right order for the commands would be:
#apt-get update
#apt-get install python-dev
#apt-get install libffi-dev
#pip install cryptography
It solved the issue in my case
You're probably running into a problem because you don't have libffi-dev installed. Installing "python-dev" and "libffi-dev" at the OS layer may help.
