While trying to solve a Non Linear Problem in Python using Openopt's NLP.solve() I get this error, summarized as
you should have DerApproximator installed.
I tried
pip install derapproximator
but it says "requirement already satisfied".
I am using Windows 7 x64, Python 3.4 with OpenOpt 0.5604. How do I install this package?
Here is the complete text from the command window.
solution = problem.solve('ralg')

Update 1
I saw a file named derapproximator-0.52-py3.4.egg in the Python34\Lib\site-packages the path which I had to add as PYTHONPATH key in the Environment variables for openopt to be found by python. I did not know how a file with .egg extension could be used there so I extracted the contents to derapproximator-0.52-py3.4. Whose folder hierarchy on cmd tree looks like
+---derapproximator-0.52-py3.4
| +---DerApproximator
| | \---__pycache__
| \---EGG-INFO
but the error is still the same,
>>> import derapproximator
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'derapproximator'
Then again I tried with renaming the folder to derapproximator-0.52-py3.4.egg but it still doesn't work.

I am trying to run the file l2cap_infra.py with Python 2, but I am getting the following error:

This might be a version conflict; I had a similar problem and I had to edit a file in /usr/local/lib/python2.7/.
What code do I have to change in that linked file or in one of my pip libraries to make this code work?
It seems it's a compatibility issue between BlueBorne and Scapy.
You (most likely) have installed the latest Scapy version (v2.4.0), which dropped the fields kwarg from scapy.layers.bluetooth.HCI_ACL_Hdr's initializer, while BlueBorne (l2cap_infra.py, and possibly others) was not updated (or branched) accordingly.
The latest version that still has it is v2.3.3 ([GitHub]: secdev/scapy - (v2.3.3) scapy/scapy/layers/bluetooth.py).
Possible solutions:
Uninstall your current Scapy version (pip uninstall scapy) and install v2.3.3 (pip install scapy==2.3.3). Probably, this is the simplest (and most suitable) for you ([PyPI]: scapy 2.3.3)
Submit a bug to BlueBorne and wait for them to add support for newer Scapy versions
Fix it yourself ("fields" (v2.3.3) to "PB" + "BC" (v2.4.0) kwargs conversion), and maybe submit a patch :)

If anyone could point me in the right direction that would be great.

Problem resolved.
I found the following support request on SourceForge which refers to a need to use short format (8.3) path and filenames in pychecker.bat and not long format as is allowed in newer versions of Windows.

I want to make an application for Sailfish OS using QML and Python. I want to have models in python and save data to sqlite using SQLAlchemy. Problem is I have no idea how can I get dependencies to my project and Sailfish OS does not have SQLAlchemy in repository. I tryed to install it using pip to lib directory in my project using
pip install --install-option="--install-purelib=pwd/lib" sqlalchemy
It installed SQLAlechemy as i expected, but when i tryed to run my project, it crashed on select with where condition - but the same code worked fine when I imported SQLAlchemy from my system.
I both installed SQLAlchemy are 1.0.8 version.
Select, which works with my SQLAlchemy installed without prefix
def getValue(self, key):
s = select([self.table.c.value]).where(self.table.c.key==key)
return self.con.execute(s).fetchone()

Know anyone whats wrong?
I think this is caused by the template you are using. Perhaps it is outdated.
Check if your setup.py looks like this:
packages=find_packages('src'),
namespace_packages=['gomobiletheme'],
But you need an additional:
package_dir = {'': 'src'},
directive to get the buildout working again.
