SystemError: NULL result Multiprocessing Python
I am using a Multiprocessing pool to train machine learners.
Each LearnerRun object gets a learner, a dictionary of hyperparameters, a name, some more options in an other options dictionary, the name of a directory to write results to, a set of IDs of examples to train on (a slice or numpy array), and a set of IDs of examples to test on (also a slice or numpy array). Importantly, the training and testing data are not read yet: The sets of IDs are relatively small and direct a later function's database-reading behavior.
self.pool.apply_async(learner_run.run), which formerly worked fine. Now the pool seems to be loaded up, but a print statement at the top of the run() function is never printed, so the processes are not actually getting run.
I've tracked down some other threads about this and found that I can see the problem in more detail with
handler = self.pool.apply_async(learner_run.run)followed by
handler.get(). This prints "SystemError: NULL result without error in PyObject_Call".
Great, something I can Google. But all I can find on this issue with Multiprocessing is that it can be caused when passing arguments that are too big to pickle to the subprocess. But, I am obviously passing no arguments to my subprocess. So what gives?
What else, aside from arguments exceeding the allotted memory size--which I am reasonably sure is not the problem here--can cause apply_async to give a null result?
Again, this worked before I left for vacation and hasn't been changed. What kinds of changes to other code might cause this to stop working?
If I do not try to
get()from the handler so execution doesn't stop on errors, the memory usage follows this strange pattern.
Error with installing numpy
My code was running fine for ages then all of a sudden my python libraries stopped working.
I tried uninstalling and reinstalling them- still doesn't work. I tried running the code from the terminal, still an error message. I ran different .py files and get the same error message:
'SystemError: initialization of multiarray raised unreported exception'
It also reads at the top of the shell:
WARNING: The version of Tcl/Tk (8.5.9) in use may be unstable. Visit http://www.python.org/download/mac/tcltk/ for current information.
I tried Python3 and Python2 too, I'm on Mac 10.11.4
I really need to fix this! Any guidance welcomed

I am using VSTS to deploy an MVC Website and a database to an Azure Virtual Machine . While trying to copy the needed dacpac file i get this error: ##[error]System error 1326 has occurred.
Here is the log from the release:

The error does not give me alot of details about the problem so i started digging deeper in the problem. I have Enabled all the needed ports, checked if the account specified was an administrator(it was), made sure the date was set correctrly(tried this because there are some examples where it works).
Azure File Copy does not help me in my situation.
Any information would be very appreciated. Thank you !!!
