I don't have experience in downloading libraries, so any help is appreciated. I've got a fresh install of Python3.3 and am trying to get IPython for 64bit Windows 7. The IPython .exe installer ran fine and completed normally, but I can't access the program. I looked through their documentation, and tried the commands there, but
$ python setup.py install
returns invalid syntax, highlighting "setup". I thought the fix might be in the distribute library mentioned on the page, so I went to go try and get that first. However, using the script from distribute's install page revealed it's own errors, namely
Traceback (most recent call last):
File "C:\Python33\distribute_setup.py", line 541, in <module>
sys.exit(main())
File "C:\Python33\distribute_setup.py", line 537, in main

self._log(WARN, msg, args)
File "C:\Python33\lib\distutils\log.py", line 30, in _log
if stream.errors == 'strict':
AttributeError: errors
I've been at it for a couple hours now, and I'm fresh out of ideas. What next?
It looks like you ran into Python bug 12967. You need to run distribute_setup.py outside of IDLE (i.e. in a command prompt).

I'm on Windows 10 and working in a git-bash terminal with anaconda environment. When I open a new terminal, I'm immediately presented with:
Error processing line 1 of C:\Users\e360769\AppData\Local\miniforge3\lib\site-packages\distutils-precedence.pth:
Traceback (most recent call last):
File "C:\Users\e360769\AppData\Local\miniforge3\lib\site.py", line 169, in addpackage
exec(line)
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named '_distutils_hack'
Remainder of file ignored
This same error comes up any time I run "pip" or "python" on the command line. The command still executes correctly, but only after displaying that error. Note that this started after installing a collection of packages needed for a project I'm working with, and after investigating I found some people attributed this to the setuptools package (I have v41.2.0), but even when I uninstall it, the issue persists. Also note that this is the contents of my distutils-precedence.pth file:
import os; var = 'SETUPTOOLS_USE_DISTUTILS'; enabled = os.environ.get(var, 'local') == 'local'; enabled and __import__('_distutils_hack').add_shim();
I'm not sure this is actively (for now) causing any issues with executing my python scripts, etc., but I'd like to know what's going on and how to fix this. Would appreciate any help!
I installed openmdao via the documentation here (windows 10 plus anaconda): http://openmdao.org/twodocs/versions/latest/getting_started/getting_started.html
If I actually use the [all] flag it seems that pip tries to download every version of the packages so I just went with pip install openmdao
When I try to run the sample from the above link I get this error:
AttributeError: 'Problem' object has no attribute 'model'
I tried re-running in spyder with the same error then tried the first few lines just in the terminal to verify no model attribute existed.
I tried to skip further down into the code with terminal and got some more errors:
prob.driver=om.ScipyOptimizeDriver()
Traceback (most recent call last):
File "<ipython-input-6-8ea598efdab2>", line 1, in <module>
prob.driver=om.ScipyOptimizeDriver()
AttributeError: module 'openmdao.api' has no attribute 'ScipyOptimizeDriver'
I assumed that maybe there is a disconnect with the different versions floating around with openmdao so I then installed the latest non-dev version and tried to run a few included files in that master folder. All the examples I ran had the same error though:
runfile('C:/Users/Vicconius/Anaconda3/OpenMDAO1-master/examples/beam_tutorial.py', wdir='C:/Users/Vicconius/Anaconda3/OpenMDAO1-master/examples')

Any ideas? THANK YOU!!
I can imagine two scenarios:
you happened to create an openmdao folder in your current local directory. You're opening the interpreter or otherwise running python scripts in that same directory. So when you try import openmdao it picks the local folder first --- instead of the installed package. If thats the case, either cd to a different directory or rename/remove that folder.
Something has gone wrong with your install. You somehow have multiple conflicting versions sitting around.
To test, first uninstall with pip:
pip uninstall OpenMDAO.
Then open an interpreter and try
import openmdao
If that somehow works, after you just uninstalled it, that confirms that you somehow have multiple installs.
you need to manually clean up your environment.
inside the interpreter, openmdao.__file__ should tell you where this wonky second install is hiding. You can go delete it manually, and then repeat this import test till you get an ImportError. At that point you know you have found all the rouge installs and you can safely retry a new pip install.
When I click on my Python IDE's (IDEL, PyScripter) they will not even open. I tried typing python in the command prompt and this is what happened:
C:\>python

TypeError: str() takes at most 1 argument (2 given)
Did you recently install ArcGIS? It looks to me like ArcGIS installed a few libraries, and overwrote your site.py, but it's using code that's meant for Python3 rather than Python2.7. The str function is capable of taking in 2 arguments in Python3 but not in Python2.
To get your Python to work again, you could try deleting the entire ArcGIS10.5 directory from your computer (or temporarily moving it to your desktop and seeing if that helps). You can also try running python -S in Command Prompt to run Python without importing site.py.
To try to get ArcGIS working, you might be able to install Python3, and reinstall ArcGIS using that.
Hopefully that helps!
I am trying to use the python 3 bindings to VirtualBox but there appears to be broken dependencies. It seems odd to me that this hasn't been fixed over the ~4 years that people have been having this issue. Perhaps I'm missing something obvious. It's been known to happen.
I have installed the virtualbox host modules, sdk, and extensions through my OS's pacakage manager. Then, through pip:
pip install pyvbox
The imports work:
from virtualbox import VirtualBox, Session, Manager, WebServiceManager
But then any attempt to instantiate anything results in an exception complaining about a missing vboxapi.
box = VirtualBox()
Traceback:
Traceback (most recent call last):

module = self._system_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'vboxapi'
There is a vboxapi on PyPi, but it won't install as there is no code associated with it, nor any useful information on the PyPi page:
https://pypi.python.org/pypi/vboxapi
Here are a couple links to the valiant efforts of braver souls than I. It is not immediately clear to me which is the correct solution or if either are still relevant, given that they are from 3 and 4 years ago, respectively.
https://github.com/GreatFruitOmsk/vboxapi-py3
https://github.com/jbuergel/vboxapi-py3
Also from 3 years ago, word of a vboxapi.diff and intergration into vboxapi:
https://www.virtualbox.org/pipermail/vbox-dev/2014-April/012231.html
I'm the current maintainer of the pyvbox package.
The VirtualBox SDK already supports Python 3, I use Python 3.5 to develop the library. I recommend uninstalling and reinstalling the latest version of the SDK (which at the time of writing this is 5.1.22).
You can find the SDK on the VirtualBox downloads page. Unzip the archive and run the vboxapisetup.py file using your system Python with the following command:
python vboxapisetup.py install
You don't need to install this in any virtualenv, as pyvbox will search your system libraries in addition to virtualenv installations for better ease of use.
If you have problems using the pyvbox package after running these steps, please open an issue and include as much information as possible including the steps you took, OS, where your system Python is located, which version of VirtualBox & SDK you're using, and I'll help you as best I can.
Yes you can, it is possible, very tricky to setup but it work fine for me now (Ubuntu 18.04 / python3.6 / virtualbox 6.0) .
The error:
ModuleNotFoundError: No module named 'vboxapi'
mean that python3 does not find vboxapi module, now there is two methods to "force-install" the vboxapi package to python3:
First Method [easy]: Assuming pyvbox is already installed and work fine with python2.7, in that case you can simply copy the package from python2.7 dist-packages to python3 dist-package with:
sudo cp -r /usr/lib/python2.7/dist-packages/vboxapi /usr/lib/python3/dist-packages
Second method [more tricky]: Go to VirtualBox, then download the last Software Developer Kit (SDK), actually the 6.0.4
Unzip the archive and run the vboxapisetup.py file using Python3 with the following command:
sudo python3 vboxapisetup.py install
You will get this issue:
Traceback (most recent call last):
File "vboxapisetup.py", line 90, in <module>
main(sys.argv)
File "vboxapisetup.py", line 63, in main
raise Exception("No VBOX_INSTALL_PATH defined, exiting")
Exception: No VBOX_INSTALL_PATH defined, exiting
You may directly edit the current file vboxapisetup.py and replace line 57, from vboxDest = os.environ.get("VBOX_MSI_INSTALL_PATH", None) to vboxDest = "/usr/lib/virtualbox"
Then run agin:
sudo python3 vboxapisetup.py install
And now you will get something like that:
running install
running build
running build_py
copying vboxapi/__init__.py -> build/lib/vboxapi
running install_lib
creating /usr/local/lib/python3.6/dist-packages/vboxapi
copying build/lib/vboxapi/__init__.py -> /usr/local/lib/python3.6/dist-packages/vboxapi
copying build/lib/vboxapi/VirtualBox_constants.py -> /usr/local/lib/python3.6/dist-packages/vboxapi
byte-compiling /usr/local/lib/python3.6/dist-packages/vboxapi/__init__.py to __init__.cpython-36.pyc
byte-compiling /usr/local/lib/python3.6/dist-packages/vboxapi/VirtualBox_constants.py to VirtualBox_constants.cpython-36.pyc
running install_egg_info
Removing /usr/local/lib/python3.6/dist-packages/vboxapi-1.0.egg-info
Writing /usr/local/lib/python3.6/dist-packages/vboxapi-1.0.egg-info
which mean that we are ok with vboxapi package installation !
Now, let's try again to load virtualbox() inside python3:
from virtualbox import VirtualBox, Session, Manager, WebServiceManager
box = VirtualBox()
this probably will raise this new issue:
Traceback (most recent call last):
File "virtualbox_python3_test.py", line XX, in <module>

raise Exception('Cannot find VBoxPython module (tried: %s)' % (', '.join(_asVBoxPythons),))
Exception: Cannot find VBoxPython module (tried: VBoxPython3_6m, VBoxPython3m, VBoxPython)
If you dig you will find a lot of questions (question 1,question 2,question 3, question 4 etc...) relative to this issue on the web ...
But according to my dig & research, if you are lucky (and have a Virtualbox built with python3 native support) you can try:
cd /usr/lib/virtualbox/
sudo cp VBoxPython3_5m.so VBoxPython3_6m.so
But if you got the following error:
cp: cannot stat 'VBoxPython3_5m.so': No such file or directory
It mean that you don't have native python3 support in Virtualbox...
This could be solved like this:
Go here and download the python3-virtualbox-5.2.16 binary package (we don't care about the VirtualBox version...)
Now open python3-virtualbox-5.2.16-lp150.4.11.1.x86_64.rpm archive, browse it to /./usr/lib/virtualbox/, then extract the file VBoxPython3_6m.so, then drop this file in your current working directory, after that from this directory you have to do:
sudo cp VBoxPython3_6m.so /usr/lib/virtualbox/
And now, you can use python3 binding for virtualbox !
I was attempting to install mitmproxy and run the "mitmproxy" and "mitmdump" from the Scripts folder.
However, I get tons of errors that a lot of modules are not found.
From the error messages I tried to install all the missing modules
Pry
PyOpenSSL
Pyasn
urwid
I stopped after that as I am not sure this will lead me to success.
a) is running and building mitmproxy on windows possible at all?
b) how can I get all the dependant modules and install them?
I reached the point where the package "urwid" is needed. However that fails with: "Unable to find vcvarsall.bat"
EDIT: it seems running mitmproxy is not really possible as the urwid package provides the terminal GUI which does not work for windows. However, I only need mitmdump. When I try running it I get:
C:\Python27\Scripts>C:\Python27\python.exe mitmdump -w out.txt

Maybe it can not find this certificate dummy file that is created. However, it didnt create the "mitmproxy-ca-cert.p12"
Help needed
mitmproxy's console interface (ncurses) doesn't run on Windows, although you can get it running under Cygwin. If you don't need an interactive user interface for your specific task, mitmdump (comes with mitmproxy) gets the job done as well. If you want to try out some alpha-quality software, you can also try mitmproxy's mitmweb and open the webinterface at http://localhost:8081/.
