Hello everybody,
I'm trying to build a python.net application using cx-freeze .
Once the application is built, I put in my final folder the Python.Runtime.dll.
but it stil doesn't seem to work . Actually, when I run the .exe file, nothing is happening.
So, I wonder if there were something else to do, another dll to put in the folder, or any option to use with cx_freeze when building the application ?
i would be very grateful if you could help me on this matter ..
Thanks in advance,
Boris
Hello,
Is there a design reason that pythonnet loads C# assemblies into its own AppDomain rather than establishing a separate AppDomain? It would be useful for instance when developing in C# in parallel with writing python code (say, in the ipython REPL) to be able to reload C# assemblies dynamically.
Also, we've found it useful in Initialize() to enable shadow copying, to prevent file locking, ie
internal static void Initialize() {
...
AppDomain domain = AppDomain.…
[View More]CurrentDomain;
// prevent file locking
domain.SetShadowCopyFiles();
domain.SetShadowCopyPath(null);
Although these are deprecated methods, and really it should be establishing a new AppDomain as above.
Regards,
Adam

Hi,
I have looked at the following thread to copy a c# array to numpy list
using python dot net.
https://mail.python.org/pipermail/pythondotnet/2014-May/001525.html
When I try the methods mentioned in the complete thread I manage to get the
array from simple iteration method or
np.fromiter, but I have not been able to make GCHandle or Marshal.Copy work
for my case.
To explain about my issue, I use a computer code written in c# which
produces output in a custom build format. I am able to …
[View More]access the data from
the file system using python dot net, but it seems that it take almost half
an hour to get the data from the file.
For example my file has an array of size 5018x73x400, if i use *fromiter, *i
provide the last bit of array to copy to python due to the way file stores
output.
for j in xrange(num_nodes-1):
for i in xrange(nsteps):
temp = file_in.ReadItemTimeStep(j+1,i).Data
temp_1 = np.fromiter(temp, float)
dest[j, i] = temp_1
Other way of doing same task would be to use a for loop but tht would be
really slow.
for k in xrange(num_nodes-1):
for k in xrange(nsteps):
for i in xrange(nvals):
temp[k,j,i] = file_in.ReadItemTimeStep(k+1,
j).Data[i]
I am trying to find a faster way to extract the data from the file. I was
wondering if there is a possibility to use something like GChandle or
Marshal.Copy. I have also attached same output from Marshal.Copy
Marshal.Copy(temp, 0,
IntPtr.__overloads__[int](temp2.__array_interface__['data'][0]), len(temp))
