Hello,

I am using Paraview as a middle man to convert data from Ensight .sos files to binary format for further post-processing. In order to do so, I read the required data and save it to a 2D array. However when I try to save it using the following lines, the program crashes with the following error message:

Inconsistency detected by ld.so: dl-close:c: 811: \_dl\_close: Assertion ‘map-\>l\_init\_called’ failed!

f = open(‘Binary\_Data’, ‘wb+’)  
binary\_format = bytearray(Matrix)  
f.write(binary\_format)  
f.close()

The code is run using: pvpython Ensight2Binary.py (name of the program)

Thank you in advance,

Alfonso

your code is unrelated to paraview. Not sure how we can help.
