pyinstaller ERROR

[mikilterribile]

Hy everyone, this is for real my last message. I had been trying for hours seeking for a solution but nothing.

I have created a nice code for running anuga with shapefiles and raster that can be directly taken as outputs of a GIS-program. The code runs correctly in each reasonable scenario and allows to easily simulate flooding events with solid transport, riverwalls, structures, culverts ecc...

Now I want to build an executable file with my work, in order to use it in each computer I want and eventually share it with other interested people.
In order to do that, I've freezed my python code and my evnironment using 'pyinstaller'.

The problem starts now. When I run my executable file with a hydraulic problem, while anuga creates the domain it raises an error: "'NoneType' object has no attribute 'write'". The mesh file is not even generated. I think the error is here around, maybe, because in the log file the last written words are:

NB: The same identical hydraulic problem gives no errors running my python code with Pycharm.

Thanks in advance for any kind of support, Best regards,
Michele Zucchelli.

@mikilterribile could you also provide the full error message. Hopefully that will indicate where the error is being produced. It could be caused by some conflict in the environment created by pyinstaller

It seems to be I found the solution. The error was due to the "pprint" statement in the mesh generation. pprint needs to a default console where to print the values and using an executable file maybe the default console is "None". So I simply removed the "verbose" option (verbose = False) in the "create_domain_from_regions" function and now it seems to work.
