Hi all,
After a lot of searching on the internet, I am looking for help from you guys.
I am working on a Qt based GUI which takes in a stream of file paths coming
from a separate process and reads those data file for post-processing and
plotting. Since post-processing and plotting have become a bit involved, there
is a request to improve the performance of the GUI. Currently the GUI takes in
the input message with the path of the file and gives a SIGNAL to the Worker
thread (Qt thread) to process the file. The processing results are saved in the
object for reference and display within the GUI. Simple separation of the
threads does not help a lot for intensive processing cases. I had to add a
sleep of 1 sec to quick fix the GIL of Python and make the GUI responsive. To
improve the solution, I thought of using Multiprocessing for the
post-processing task. I am trying to add the task to queue and get back the
result in a queue. When I implement this solution, I get 'TypeError: cannot
serailize '_io.TextIOWrapper' object' at the call of start() of the Process.
What could be the cause of this error? Is there a better way to solve this
issue? Any suggestions are welcome.
Regards, Akshay Verma
