Pyplot Not Working With Pyinstaller. Exe Crashes With No Errors - windows-10

I'm working on my first gui exe. I'm using the anaconda packages with spyder and the code works fine there. Math, pyplot, numpy, tkinter, and PIL are imported, and the app is fully functional with the exception of pyplot which will not show up when activated from a button widget.
If instead I create a simple exe with the code:
import numpy
import matplotlib.pyplot as plt
x=numpy.linspace(1,100)
fig,ax=plt.subplots()
lineData,=ax.plot(x,3*x)
I get one error during the initial build:
ModuleNotFoundError: No module named 'Crypto.Math'
and many warnings, but note that the analysis warning file contains no errors either.
Running the created exe, I get failure and cmd exits. Running from cmd initially instead and turning on debug and verbose imports yields tons of warnings, but no errors.
I've tried including hidden imports like 'matplotlib.pyplot','matplotlib','Crypto', and importing Crypto, to no avail. Crypto is not being called anywhere and the reference plot in the build folder says only pyinstaller imports it. I'm at a loss here for what the problem could be.
Packages in anaconda folder

Ok, so it turned out to be a simple fix. lineData,=ax.plot(x,3*x) will plot/show the figure in spyder/Ipython, but not when called in the exe or python standalone, so I had to add plt.show().
From there I made a virtual environment with the latest packages and needed to
downgrade numpy to 1.16.2 per this thread, and now everything works.

How to actual plot properly via Plotly

I have a problem with the plotly package. To be precise, I'm using auto-py-to-exe in order to have a file .exe which, if the users asks for it, plots a table using the plotly package. My code goes like this:
import pandas as pd
import plotly.graph_objects as go
import numpy
df= pd.read_excel (r'C:\Users\user\Desktop\Program\Data_Studio_Def.xls')
visualize_table= input('visualize table of patologies? (yes/no)')
if visualize_table== yes
fig = go.Figure(...)
fig.show()
Now, when I run the .exe made by auto-py-to-exe on the CMD (OS: Windows 10), I get some errors regarding modules like
Module plotly.validators.table not found
Once I add all such modules via hidden-import, I get the error:
FileNotFoundError No such file or directory : C\Users\user\output...
so it is searching for the plot in a folder rather than actually print it and I don't know how resolve this. Should I provide further informations?
P.S. I found out that the main problem is caused by the plotly package itself: I tried to build the exe via cx_Freeze rather than pyinstaller and the result was:
Module plotly.validators.table has no Attribute CellsValidators
Doing some searching I found out I'm not the only one with the same problem, the "HasNoAttribute", but uninstalling the package to then reinstall it again didn't do anything unfortunately.

Beginner having a problem with matplotlib

I am using the book Python Crash Course as a textbook. I was doing pretty well until I tried to use the Matplotlib library. The book gave the following command to install the library:
python -m pip install --user matplotlib
I entered this in the terminal window in Pycharm (the IDE I am using). It appeared to work, in that I got a series of messages indicating that files were being downloaded and installed on my computer. However when I attempted to import matplotlib.pyplot into an example piece of code I was trying to write, I got a ModuleNotFoundError: No module named 'matplotlib'
I assumed that the downloaded module went to the wrong directory, so I searched my hard drive to find a file or folder named matplotlib. I found several folders in different locations, but when I tried copying them into folders where I knew Pycharm could find it, it didn't seem to help. Can someone please clue me in to how I can use this module.
I am using windows 10 on an MS Surface 6.

Pyinstaller does not properly include numpy in Mac bundle

If I include numpy in my script the bundle application does not even open. However, if I run the application from the console everything is fine. So:
pyinstaller -w myScript.spec
with import numpy as np in one of the modules does not create a proper executable. However:
python3.7 myScript.py
runs without problems. Even more, if I comment the import numpy as np line the executable is created without problem. I have also used numpy in another console-only script without problems.
So, how can I make PyInstaller include numpy in the bundle app?
I checked the warn-myScript.txt file from PyInstaller and there are lots of modules from numpy.core that are not found, for example: numpy.core.sqrt.
But I have no idea where to find these modules.
I tried doing what j4n7 suggested here, but it did not work.
I am using Python3.7, numpy 1.15.4 and PyInstaller 3.4
I installed Python from the Python web page and numpy and Pyinstaller using pip.
In a different computer I installed Python3.7 from homebrew and I have the same problem
I installed miniconda and then created an environment with numpy 1.15.4, Pyinstaller 3.4 and python3.7.1. Within the environment, I can create the bundle app with no problem.
However, the bundle app goes to 600MB. I will start a new question regarding how to reduce the size of the bundle app.

PyCharm Import Error: Claims 'matplotlib' is not a package, but works successfully in IDLE

Happy October everyone,
I've successfully downloaded modules before using either the pycharm installer or pip through the command screen, but for some reason when installing matplotlib pycharm cannot recognize it. I've uninstalled and reinstalled, I've installed through both methods, I've followed past similar questions asked on this site which make sure that you have the same interpreter and that it was installed in the right folder (pycharm error while importing, even though it works in the terminal).
So, here's the whole problem. Here's is the simple code, submitted into both pycharm and IDLE:
import matplotlib.pyplot as plt
plt.plot([1,2,3],[2,1,3])
plt.show()
When submitted into IDLE, my plot appears. When submitted into pycharm, the following error appears:
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/PythonProject/matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
File "C:\PythonProject\matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
ImportError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
I am currently running Python 3.4, PyCharm 2016.2.3, and my matplotlib folders are indeed in my site-packages folder inside my Python34 folder. Also for further verification:
PyCharm installation
Please help I've become frustrated since this is the only module I've run into trouble with. I've scoured StackOverflow and related websites to help, I've made sure I have all the requirements, etc.
I guess if you named your current writing python module as matplotlib.py.That cause the python load your current writing module instead of the actual matplotlib.py, which triggers an error.
I recommend you to use virtualenv. Is not strictly necessary but is good for dividing your project environments.
This is how I tested matplotlib on my Windows 10 installation, hope it helps.
Be sure that you have the python 3 installation folder listed in your Windows PATH environment variable, should be already listed if you checked "Add Python 3.5 to PATH":
You need also to set the Scripts folder in your PATH environment variable usually should be this path:
C:\Users\<your username>\AppData\Local\Programs\Python\Python35\Scripts
If you don't do that you have to prepend python -m to every command below like this: python -m <command>, so the command below would be python -m pip install virtualenv. I prefer the first solution.
To test matplotlib on Pycharm I've used virtualenv, here is how; first install virtualenv:
pip install virtualenv
Then you create your virtual environment in a folder of your choice, in my case I used python_3_env_00:
virtualenv python_3_env_00
After that you can activate you python 3 virtual environment:
python_3_env_00/Scripts/activate.bat
Now you should see in your command line the active virtual environment (python_3_venv_00), like this:
Now you can install matplotlib:
pip install matplotlib
Fire up PyCharm and add your virtual environment as you project interpreter, go to File->Settings search for Project Interpreter click on the gear icon and Add Local and set the path of your virtual environment, should look like something like this:
Test it:
import sys
print(sys.path)
run this code in where the import worked, and run it in the Pycharm project. Compare the lists. Find out which path that is not present in Pycharm sys.path.
Before importing pyplot, append the missing path to sys.path.
import sys
sys.path.append("the path")
import matplotlib.pyplot as plt
Does this work?
Please follow below steps if you are still getting an error:
If you are using PyCharm, it automatically create virtualenv.
Ensure Scripts path is set into PATH
C:\Users\<Username>\AppData\Local\Programs\Python\Python37-32
Then open PyCharm and go to File-> settings. Search for Project Interpreter. You will see window like this
sample image
Click on setting icon -> Existing Environment -> click on ... give below path
C:\Users\Krunal\AppData\Local\Programs\Python\Python37-32\python.exe
Click on Apply -> ok and you are good to go.
After installing matplotlib When I was trying to use matplotlib.pyplot it was giving error module not found.
I browsed some white papers and found out that we also need to install scipy library to use the matplotlib so I used the below in my command prompt
python -mpip install scipy
Restarted my kernel session.
It worked!!!
I was also facing issue while importing matplotlib but it got resolved and now I am able to use it from pycharm as well.
Please make sure you should have visual c++ 14 installed in your system.
2.If you have more than two python version installed on your system then please install matplotlib from both the version.
Eg. pip install matplotlib
pip3 install matplotlib
If matplotlib is working from python idle then please check whether you are using correct interpreter in pycharm or not and try to choose pythonw.exe path from your installed location.
Hope this will help, Please do let me know if you are still facing issue.
I had similar issue but I solved it very easily on pycharm 2019.3.2. In case anyone looking for an easier solution:
I just opened the terminal window on pycharm and typed pip install matplotlib and it was all good to go. Every project has its own virtual environment. Opening terminal window of IDE cds to project directory by default. So the installing command was enough.

cx_freeze and scipy: "ImportError: cannot import name vode"

i am trying to create an executable from my python script. My script runs fine, but after freezing it, starting the .exe gives me the following error:
http://www.bild.me/bild.php?file=4663406scipyerror.png
I am using Python 3.2.3, Scipy 0.12.0b1, Numpy 1.7.0 and Matplotlib 1.2.0 (all 32bit).
Any ideas/hints on how to solve this? My guess is i have to include something manually in my freezing script, but i am running out of guesses :-(
I got it finally to work, but I am very unsatisfied with my solution:
1) copy _odepack.pyd and odepack.py from the SciPy package to my program folder
2) in odepack.py change from . import _odepack to import _odepack (otherwise ValueError: Attempted relative import in non-package is raised)
3) in my main change from scipy.integrate import odeint to from odepack import odeint
Now it is working as expected and after using cx_freeze it is still working.
Still got no idea why it would not work before :-(
Thanks ThomasK for pushing me in the right direction though :-)
I finally got around this vode-problem by specifying "scipy.integrate.vode" as an include in the cx setup-file. This resulted in a file "scipy.integrate.vode.pyd" to end up in the build folder. I am using SciPy 0.11, Python 3.2.3 and the latest cx on Windows.
But adding such a "scipy.integrate.vode" file manually to the build folder would not fix the problem for me either, even though such manual-include-fixes were needed for many other .pyd files cx could not find either (and whereby the above setup.py include-solution would not work instead)...
Thanks for sharing your distress and wisdom, would not have managed to freeze my program otherwize...
