# How can I use Numerical Python with Python 2.6

I'm forced to upgrade to Python 2.6 and am having issues using Numerical Python (NumPy) with Python 2.6 in Windows. I'm getting the following error...

```
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
from numpy.core.numeric import array,dot,all
File "C:\svn\svn_urbansim\UrbanSimDev\Builds\working\urbansim\Tools\Python26\lib\site-packages\numpy\__init__.py", line 39, in <module>
import core
File "C:\svn\svn_urbansim\UrbanSimDev\Builds\working\urbansim\Tools\Python26\lib\site-packages\numpy\core\__init__.py", line 5, in <module>
import multiarray
ImportError: Module use of python25.dll conflicts with this version of Python.
```

It appears that the existing module is trying to use the `python25.dll`

file. Is there any way I can tell it to use the `python26.dll`

file instead without modifying the source code?

# Answer 1

How did you install it? NumPy doesn't currently have a Python 2.6 binary.

If you have LAPACK/ATLAS/BLAS, etc. and a development environment you should be able to compile numpy from sources. Otherwise I think you're stuck with using Python 2.5 on Windows if you need NumPy.

The next version of NumPy should have a 2.6 binary, and it's likely to be out within the next month or so.

[Edit]: It appears that a pygame developer created a NumPy 1.2.1 binary for Python 2.6 on Windows, available here.

# Answer 2

NumPy 1.3.0 is available for Python 2.6 now.

python - How do I assign a numerical value to each uppercase Letter?

How do i assign a numerical value to each uppercase letter, and then use it later via string and then add up the values.

python - Sorting list of lists with mixed numerical values

Scenario: List containing 'rows' of list records with a variety of values
Problem: List.sort doesn't take the numeric values into consideration so values end up all over the place

I've tried using
list.sort(key=operator.itemgetter[index])
and doing a

python - Sort a list of numerical strings in ascending order

I have created a sqlite database which has a table which stores temperature values. The temperature values are written to the database in ascending order for the first time. Then I read the temperature values from the database into a list and then add that list to a combo box to select temperatures - works fine.
The resulting list is, say:
templist = ['25', '50', '100', '150', '200', '250', '300']....

python - In scikit learn, how to deal with the data mixed with numerical and nominal value?

I know that the computation in scikit-learn is based on NumPy so everything is a matrix or array.
How does this package handle mixed data (numerical and nominal values)?
For example, a product could have the attribute 'color' and 'price', where color is nominal and price is numerical. I notice there is a model called 'DictVectorizer' to numerate the nominal data. For example, two products are:

python - Mixing numpy and OO in numerical work

First, I'd like to know if it's good practice in general to use an OO approach in numerical work.
Second, a possible use case for OO would be to encapsulate in some object the parameters of some model. Say, I want to study parabolas of the form ax^2 + bx +c. So I would encapsulate a, b, c in some Parabola object. I can plot it and so on. Now, let's say, I want to explore the location of the vertical axis of parabol...
