Neural Networks on Python

Calling Python from Matlab
Neural Network that has

It is sometimes useful to call Python from Matlab. There may be a robust implementation of an optimizer that hasn’t been well-ported to Python yet. What to do in this situation?

There is a simple strategy that should do: first, figure out how to call python from stand-alone C functions, and then use that code within a mex function. While tedious, at least this is straightforward. By using the not terribly complicated PyObject stuff we can create python objects in C, send them to python functions, and unpack whatever the python functions give us back.

However, everything goes bad if we try to import numpy in our python code. We’ll get an error that looks like this:
……../pylib/numpy/core/multiarray.so:
undefined symbol: _Py_ZeroStruct
even though all the required symbols are defined in libpython2.x.

This problem was asked several times on stackoverflow, with no satisfactory answer. But luckily, after much searching, I stumbled upon which discovered a way to solve this problem.

Basically, matlab imports dynamic libraries in a peculiar way that messes up the symbols somehow. But if we execute the code

int dlopen_python_hack(){
if (!dlopen_hacked){
printf(“Preloading the library

Your child is expected to be

Supported by both parents. However, remember the other parent is supporting the child when she is there. They are feeding the child,paying for activities etc. Whether they have to provide any money to you depends on many factors.You should google the child support calculator for CA.I would first try to work out a parenting plan. If the child can only see the parent once a month,what can you offer in exchange? more time over the summer? extra school breaks? This is not a drastic change but be ready to make up for the lost time. Also, let the other parent know that any time they want to come to CA they are welcome and can go to the activities with the child
