Upon installing python xy 2.7.5 on my laptop, I tried to launch the Spyder IDE. This yielded the following error:

Using a python console, I was able to run python code as well as matplotlib and numpy code. Ipython works, however Ipython (Qt) does not work. what could be the reason for this?
The host OS is Windows XP.
This is actually a problem with the most recent builds of zeromq, which are messaging libraries that are required for IPython, and not with Spyder itself. The latest zeromq builds are not compatible with Win XP. This is a know issue with recent versions of Python(x,y) on Win XP which can be solved by following the guidance in this bug report.
It works by installing
https://pythonxy.googlecode.com/files/pyzmq-13.0.2-4_py27.exe
and
http://h5py.googlecode.com/files/h5py-2.1.3.win32-py2.7.msi
,

I had a previous version of Anaconda 2 (working with Python 2.7), which I uninstalled to newly install Anaconda 3 (to work with Python 3.x).
While the previous Anaconda 2 was working fine, the newly installed Anaconda 3 throws the following error:

I am using Linux Mint 19 with the following info:
...$ cat /etc/linuxmint/info

A quick google search showed that an issue was open about your problems few days ago in github
Fortunately a workaround was posted:
Editing the file: ".../anaconda3//lib/python3.7/site-packages/anaconda_navigator/api/external_apps/vscode.py"
By declaring the variable outside the loop.
Just add the line:
DISTRO_NAME = None
on Line 159 and indent it in line with the if above it (Outside it)
I got a similar experience this morning. But I was able to resolve mine by typing this into my command-line interface(CLI).
conda update anaconda-navigator
I hope this work for you.
I am trying to follow instruction from Enthought support website To test of what I have done i run line:
_python.exe canopy-script.pyw -d
Unfortunately this gives Traceback:

After "Search" I can see many of bootstrap.py files on the disc.
What would be the solution for this problem?
The current version of Canopy is 2.1.9. (You are running v 1.7.4).
To update Canopy, and for a link to release notes, please see "Installing a new Canopy version".
After you update, see:

I got this estructure, that works in eclipse, but I got a import error in cmd. I tried sys.append.path but it does not works.
I´m running main.py
python main.py
In eclipse running the same code, ctrl+f11, it works fine.
Principal\__init__.py
Principal\lib\_init__.py
Principal\lib\functions.py
Principal\App_user\__init__.py
Principal\App_user\main.py

I got in User_Controller.py, from Principal.lib import funcionesDB it works in eclipse but it doesn't in cmd.

you may need to change you directory to where you code is, and then run it in cmd line like: python main.py, or you may need to specify the directory of your code just like: python "path of code"/print_test.py.
I have google-cloud-storage pip installed into a lib directory and vendored in. It's running just fine locally during development of my python appengine app. However, when trying to run unit tests via nose and testbed I'm getting "The 'google-cloud-core' distribution was not found and is required by the application". Here is the stack:

Any thoughts?
I had the same issue with google-cloud-translate, I was forced to also install the package "globally", i.e. pip install google-cloud-translate.
After struggling a lot with this same issue I found out that the error was because the vendor pip lib wasn't in the PYTHONPATH before calling the nosetests.
Try adding the vendor lib to the PYTHONPATH and then run the tests.
export PYTHONPATH="$(HOME)/Projects/myproject/pip_lib:$$PYTHONPATH"; \
nosetests .
I am currently working with Gurobi solver using python. Previously, I have just been using a mix of a text editor and the terminal to write and run my models but I am currently experimenting with using Enthought Canopy Editor. I have a model that is works when I run in in the terminal using python model.py but when I try doing%run model.py in Canopy's iPython shell I get:
%run /home/cdhagmann/Copy/Code_Env/Farmer/model.py
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

ImportError: No module named gurobipy
My guess is that the terminal and Canopy look for modules in different places but I don't know how to rectify it. I found this reference on the Gurobi group site about Enthought Canopy and Gurobi on OS X 10.8 but didn't know how much those instruction would differ from doing it on Linux and even what he meant about installing Gurobi in Canopy's site-packages.
UPDATE: Based on information found the first link I clicked on, I did in fact leave the boxed clicked making Canopy my default directory. You have to manually prepend the PATH variable, which I missed them saying that I had to do. So I did that. I now have Canopy's version of iPython running in my terminal (check by using sys.path); however, I get a huge list of errors when I try run python.

If the terminal is correctly configured for Canopy Python, then python in terminal and Canopy Python should be looking for modules in the same places. If during installation, you disabled "make Canopy be default Python", or if you have not restarted terminal since installation, then it won't automatically be configured correctly.
These articles should help you understand and configure:
http://docs.enthought.com/canopy/configure/faq.html#where-are-all-of-the-python-packages-in-my-user-python-environment
https://support.enthought.com/entries/23646538-Make-Canopy-s-Python-be-your-default-Python-i-e-on-the-PATH-
https://support.enthought.com/entries/23389761-Installing-packages-into-Canopy-Python-from-the-command-line
If these articles do not suffice for you to solve this, then please report -- when you run python from terminal, what are these?
