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.

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):

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.
When trying to import gurobipy i get the following ImportError:

Since searching google resulted in errors related to environment variables and 64 vs 32 bit Versions i checkt those.
I am running the 64 bit Versions of Annaconda (3.6 using a 2.7 env) on Windows 10 and Gurobi
Gurobi is installed according to this instruction (including the license): http://www.gurobi.com/downloads/get-anaconda
The GUROBI_HOME variable is correctly set to C:\gurobi702\win64 and the Path variable to C:\gurobi702\win64\bin
Python Path variables are set.
Following packages are installed: gurobi 7.5.1, mkl 2017.0.3, numpy 1.13.1, pip 9.0.1, python 2.7.13, setuptools 27.2.0, vs2008_runtime 9.00.30729.5054, wheel 0.29.0, wsgiref 0.1.2
Starting the gurobi console via cmd gurobi works fine.
I reinstalled my complete python environment multiple times and tried restarting after installation.
I got it running with a new conda environment and installing via python setup.py install, as mentioned by Greg Glockner and sascha.
This problem [from .gurobipy import] is caused from the IDE Pycharm on Ubuntu. I am not sure if you may face it with the other IDEs .
First You can make sure from the shell the python has gurobipy installed.
after you installed from the file Gurobi ~\gurobi752\win64
python setup.py install
then just run python from the shell as normal python command
python yourFileName.py and gurobi will works perfectly
In windows 10 i added the path of gurobi to the IDE pycharm
after python setup.py install and pip tool for gurobipy https://sites.google.com/site/pydatalog/python/pip-for-windows, then i added the path
Settings->Project Interpreter-> show all -> interpreter paths -> add your gurobi path
I hope it works cheers ;)
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 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

You are getting this error locally because your Python27 doesn't have a prerequisite component installed. In particular it needs Pywin32 installed. You need to download and install Pywin32 from here (specifically the 2.7 version in your case). PythonShell GUI must have this extension already installed so it works.
Finally I was able to resolve my problem(Thanks to #MichaelPetch). I tried this simple example test.py
from winpexpect import winspawn
child=winspawn("java")
It was working fine. Then I realized something wrong with my imports or dependencies. I was using wexpect.py which is another alternative for windows. I renamed it to pexpect.py and copied to my code base.
But winpexpect has dependencies for pexpect(it has another pexpect file on its own folder). When I try to run my .py through cmd it is referring the file in the same folder which is pexpect, I just renamed.
Solution: I just removed wexpect.
I cannot successfully run the first command in the Scrapy tutorial (http://doc.scrapy.org/en/latest/intro/tutorial.html). The code copy pasted below is the result (with the error at the end).

I had this problem due to another (older?) version of libeay32.dll and ssleay32.dll being on the PATH before those of my own OpenSSL 1.0.1g installation. I recommend you use Process Monitor from SysInternals to monitor python.exe to see where it is actually loading your OpenSSL DLLs from.
In my case, the offender was some Intel components at C:\Program Files (x86)\Intel\iCLS Client\ that came with my drivers. After moving my own OpenSSL bin directory earlier in the PATH environment variable, everything worked as expected.
this is due to _Cryptography_cffi_48bbf0ebx93c91939.pyd depends on openssl dll ssleay32.dll and libeay32.dll. after you compile openssl on windows, u can copy these 2 files to system32.
#crazyzh1984's method is a little complex, but his supplement that posted at the bottom of his answer is very useful. I download the "Win32 OpenSSL v1.0.1g Light" at http://slproweb.com/products/Win32OpenSSL.html and then I could install pyOpenSSL successfully.
#lambokini is right，but i'cant comment on the answer, so come this one.
First download openssl source from http://www.openssl.org/
Second start "Visual Studio Command Prompt", compile and install openssl follow install guide(INSTALL.W32 or INSTALL.W64).
Then add "[openssl install path]\bin" to the environment variable "path",
and you can delete ssleay32.dll and libeay32.dll under system32.
Notice: dll will be load from the first place it seached.
for exmple: Path=xxx;d:\PHP5;d:\openssl\bin;
if ssleay32.dll and libeay32.dll also appears under PHP5,
then python will load that one.
I'll write my own take on this due to my extreme frustration and hopes that this might help some other poor chap with his issues getting scrapy to work on windows..
Had a similar issues with faulty libeay32.dll and ssleay32.dll, or so it would seem, but confirmed it with Process Monitor.
It all went to hell after those dll's were found in System32:
So i wasnt suffering from wrong PATHs (but i did change their order so system32 comes before C:\Program Files (x86)\Intel\iCLS Client\.
Next i used this site the other guys here pointed to. Ive used Win32 OpenSSL v1.0.2j Light, since the newer one (1.1.0b) didnt generate these dlls for me for some reason.
Generate them in a different bin folder so you see they are new, and then copy them to system32. Voila, scrapy command line works.
Also, as of today, anaconda's scrapy 1.1.2 does not create a key file for running scrapy commands, ive opened and closed a question about this issue here.
As others have said above, there are two .dll files that are loaded instead of the openssl that is downloaded with Scrapy. Those two .dll files are not compatible.
I resolved this by placing the downloaded .dll files (i used Anaconda to install scrapy) as a higher priority in the Environment Variables as shown in the attached image.
In Environment Variables, within System Variables and the "Path" i placed the Anaconda3 location as shown above at the top and therefore makes it the priority when python comes to load openssl
As already mentioned in the other answers, the issue is caused by the two files ssleay32.dll and libeay32.dll.
The error occurred when importing OpenSSL in Python
>>> from OpenSSL import crypto, SSL
Traceback (most recent call last):

ImportError: DLL load failed: The operating system cannot run %1.
Here's how I solved the issue on Windows 10. If you have git for Windows (download here) you can just copy these two files from Git\mingw64\bin\ to some location in your path. What worked for me was to copy them to c:\Windows (or else to the folder from which you're starting Python).
To find the locations of the dll files type at a cmd prompt:
>where libeay32.dll
C:\Program Files (x86)\Intel\TXE Components\TCS\libeay32.dll
...
C:\Users\me\AppData\Local\Programs\Git\mingw64\bin\libeay32.dll
I ran across this error today on a Windows 7 system. The problem for me was similar to #user2314737, #voetsjoeba, and #Olegp. libeay32.dll and ssleay32.dll where in folders related to Intel that were in the Windows path environmental variable.
Unfortunately, my system is locked (work computer), so I could not move the files or alter the system's path variable. Instead, I manually removed the Intel related items from the path variable that Python accesses using:
import os
os.environ['path'] = ';'.join(
filter(lambda x: 'intel' not in x.lower(), os.environ['path'].split(';'))
)
import OpenSSL
