I'm trying to create a .exe file from a .pyw python file using PyInstaller.
I am using the command pyinstaller --onefile sysTray.pyw but I am always getting an AssertionError I read around to try and debug the error but couldn't arrive at a conclusion. These are the last few lines before the error.
File "c:\users\elkha\anaconda2-32\lib\site-packages\PyInstaller\archive\writers.py", line 370, in add
code = get_code_object(nm, pathnm)
File "c:\users\elkha\anaconda2-32\lib\site-packages\PyInstaller\building\utils.py", line 545, in get_code_object
co = _load_code(modname, filename)
File "c:\users\elkha\anaconda2-32\lib\site-packages\PyInstaller\building\utils.py", line 521, in _load_code
assert loader and hasattr(loader, 'get_code')
AssertionError
My ultimate goal is to then use innosetup to create an installer for the application. I was using py2exe before the complete this task but I also ran into problems so I decided to switch to pyinstaller but it seems that there are issues with pyinstaller as well.
Any help would be appreciated.
I have Anaconda Python 2.7 (32-bit) and I installed PyInstaller 3.2 from their website

Background: I am trying to install the cling c++ interpreter here. I am on a Windows and have had Anaconda running well, Jupyter notebook also working fine with the existing Python kernels. The installation process was smooth on the surface but there is Kernel error once I try to open Jupyter notebook on the installed Kernel.
(In the end I would hope to be able to use c++ with Jupyter notebook so if anyone has had any success please could you share your experience. On that, while the xeus-cling is not usable for Windows as many say, this cling appears to be a separate thing)
The installation: Here is what I have done:
Download the binary cling_2019-11-28_arm64.tar.bz2 (is this correct for Windows?) from
https://root.cern.ch/download/cling/
Extract and place in Program Files folder
Following the instruction in here, add C:\Program Files\cling_2019-11-28_arm64\bin to the PATH variable
Activate base Anaconda environment
cd .../share/cling/Jupyter/kernel
pip install -e .
jupyter-kernelspec install --user cling-cpp11
Every thing seems to be fine up to here, no warning/error.
The error: Then I load up my Jupyter notebook and try to run the cpp11 kernel, but it is unable to start with a long error traceback, the first/last items of which read:
Traceback (most recent call last):

And on the cmd the following:
[E 14:39:14.265 NotebookApp] Failed to run command:
['jupyter-cling-kernel', '-f', 'path\\to\\jupyter\\runtime\\kernel-..(random string here)..json', '--std=c++11']
The troubleshooting (1): ... appearing to suggest that it is unable to locate a jupyter-cling-kernel. But I do have file named jupyter-cling-kernel in the .../Anaconda3/Scripts folder, and this folder is also in my PATH variable. After opening it, I discovered it is a python file with only a few lines. Looks like it corresponds to the command above.
#!C:\ProgramData\Anaconda3\python.exe
# EASY-INSTALL-DEV-SCRIPT: 'clingkernel==0.0.2','jupyter-cling-kernel'
__requires__ = 'clingkernel==0.0.2'
__import__('pkg_resources').require('clingkernel==0.0.2')
__file__ = 'C:\\Program Files\\cling_2019-11-28_arm64\\share\\cling\\Jupyter\\kernel\\scripts\\jupyter-cling-kernel'
with open(__file__) as f:
exec(compile(f.read(), __file__, 'exec'))
so then I modified my kernel.json file, adding the absolute python path (so that it knows to run it with python) and the absolute path of the jupyter-cling-kernel. (originally it was just "argv:["jupyter-cling-kernel", "-f", ...)
{
"display_name": "C++11",
"argv": [
**"C:\\ProgramData\\Anaconda3\\python.exe",
"C:\\ProgramData\\Anaconda3\\Scripts\\jupyter-cling-kernel",**
"-f",
"{connection_file}",
"--std=c++11"
],
"language": "C++"
}
The troubleshooting (2):... which indeed appears to be the right direction, at least it is running sth but now another error:
Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\Scripts\jupyter-cling-kernel", line 7, in <modu

from fcntl import fcntl, F_GETFL, F_SETFL
ModuleNotFoundError: No module named 'fcntl'
Now with some googling this fcntl appears to be sth not for Windows. So at this point I am wondering have I downloaded the wrong binary or should I modify this clingkernel.py file or do I need to do some compilation myself?
Again, if any of you knows of how to get the c++ run of Jupyter (on windows), appreciate if you could share your experience. Thanks.
With Windows 10 + WSL, we can install xeus-cling for C++ on Windows
Steps includes
Enable Ubuntu on WSL
Install Miniconda
Setup Conda, Jupyter Notebook, Xeus-Cling
This cling notebook with the cpp environment can be made to run from a desktop shortcut. Steps are documented on C/C++ Jupyter Notebook using xeus-cling - Windows WSL Setup
The cling interpreter has been packaged for conda-forge.
You can simply run
conda install cling -c conda-forge
and then run cling. However, unfortunately, the Jupyter kernel is not included with that build, and the windows build has some issues with IO operations which I am currently investigating.
Maybe try restarting the kernel by pressing o(not 0) twice.
I am using a Python 2.7 virtualenv with the MySQLdb package installed.
If I run Python from the command line and execute import MySQLdb, this works without error. If I run it from the PyCharm terminal, however, I get an error:
ImportError: libmysqlclient.so.20: cannot open shared object file: No such file or directory
The same pattern occurs if I execute a file test.py containing the line import MySQLdb. It works when executed from the command line and crashed when executed from PyCharm.
I have googled the error and it seems that uninstalling and reinstalling MySQLdb could fix it. But I would like to understand why the error only occurs in PyCharm.
I have made sure that both the command line and the PyCharm terminal use
the same virtual environment (by checking sys.executable)
the same working directory (by checking os.getcwd())
the same path (by checking sys.path)
I have also checked that PYTHONPATH is undefined.
What other difference could there be?
You have to point pycharm to your virtualenv. Go to settings -> project interpreter and give pycharm the path to your python executable. Once there it should work. Note if you have a hybrid WSL/windows setup you will need one virtualenv for WSL and a separate virtualenv for windows/pycharm.
I'm trying to run a code as described here.
I have a anaconda enviroment with tensorflow installed via pip installation.
When trying to run the example on the link provided I have a issue. The first one was that the file:ptb_word_lm.py wasn't present on my installation. I just copied the file from github and tried to run anyway. I got the following error when running python ptb_word_lm.py --data_path=/tmp/simple-examples/data/ --model small

I have found people on google suggesting to change the line from tensorflow.models.rnn.ptb import reader to just import reader, but it doesn't seem to work for me.
Does anyone know the possible solution?
I'm using Python 2.7.12 and Tensorflow version seems to be 0.11.0rc2
My computer's OS is 64-bit win 10. Python 2.7, 32-bit.
My code is plot.py, simple as below:
import matplotlib.pyplot as plt
import FileDialog
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()
When I execute pyinstaller -F plot.py, the generated
plot.exe works as expected on my current computer. However, I get an error if I try to run it on a different 32-bit Windows 7 computer:

You can try downgrading pyinstaller to v3.1 and rebuilding your exe file on your first computer to solve this issue.
Alternatively, you can fix it on your second computer by setting the TCL_LIBRARY environment variable to C:\Python27\tcl\tcl8.5\ (or wherever tcl8.5 is located)
PyInstaller has a known issue with Tkinter applications on Windows 7 and Windows XP.
Since this issue has gone unfixed for two years, I've gone ahead and started a bounty. Until the issue is fixed, there are a few workarounds you can try:
Workaround 1 - Manually copy missing files
As mentioned in a related issue, you can manually copy the missing files from your local Python installation.
Find your local Python installation. (%LocalAppData%\Programs\Python)
Make a copy of the missing folder (...\Python36-32\tcl\<missing_folder>)
Move the copy to your application's tcl folder (...\dist\<app_name>\tcl\<missing_folder>)
Workaround 2 - Run with --onefile
Running PyInstaller in --onefile mode seems to avoid this issue.
However, note that running in single file mode will increase startup time.
Workaround 3 - Downgrade to PyInstaller 3.1.0
pip install pyinstaller==3.1.0
According to ugoertz, downgrading to PyInstaller 3.1.0 resolved the issue.
Downgrading to 3.1.0 (and also downgrading setuptools to 19.2 because of the problem described in #1941) fixed the issue for me.
I'm having trouble running some codes that import cx_Oracle in command line, though the same codes work in console. Is there anything else I will need to set up in order to get this to work via command line please?
Saved just one line of code "import cx_Oracle" as test.py.
Run this line in ide (Spyder), iPython Notebook => no issues
run this by opening a command line window from the same folder the .py file is saved in, and run python test.py and encounter the below:
import cx_Oracle
ImportError: DLL load failed: %1 is not a valid Win32 application.
Not sure if there is anything additional I will need to set up to run cx_Oracle via command line? Have tried all the suggestions on setting PATH, ORACLE_HOME, re-installing but could not get this to work. versions that i'm using are
Python: 2.7
cx_Oracle: cx_Oracle-5.1.3-11g.win-amd64-py2.7
instant client: 12.1.0.0
Windows: 7 Enterprise
I also found this kind of problem.
Look at "not a valid Win32 application" this sentence, so I decide to change cx_Oracle to cx_Oracle-5.1.3-11g.win-32-py2.7. Luckly, it does work.
