xCode & iOS : Debugging with Leaks - memory-leaks

I am using Instruments Tool ( Leaks ) to diagnose the leaks, but I don't quite understand how I can backtrack to my codes. Does anyone know how can I further diagnose ?
Using Xcode 4.5 & Profiling on iPad (iOS 4.3.5).
UPDATE: Here is the backtrace :

UPDATE : Instruments with Extended Detail. Still not pointing to source. It points to machine code instead.

If you open the extended detail view, you should be able to see the call stack when you select a leak from the detail view. In addition, switching to the call tree view can help you determine where the leaks are occurring in your code. Use the jump bar to switch to the call tree view.
When you switch to the call tree view, you should see a series of checkboxes to the left of the call tree. Selecting the Invert Call Tree and Hide System Libraries checkboxes allow you to find your code in the call tree. Double-clicking one of your functions in the call tree will show you the lines of code that allocate leaked memory.

In pytorch, how to debug the JIT error information "RuntimeError: Only tensors or tuples of tensors can be output from traced functions"?

I wrote a simple pytorch Sequential module for which I plan to convert to ONNX for visualisation & mobile deployment. The first step is to convert it into JIT version:
input = torch.rand(1, 3, 300, 300, dtype=torch.float32, device=device)
mod = FPNImproved(raw)
torch.jit.trace(mod, input)
This step gave me the following error:
for method_name, example_inputs in inputs.items():
# this is needed since Module.__call__ sets up some extra tracing
func = mod if method_name == "forward" else getattr(mod, method_name)
example_inputs = make_tuple(example_inputs)
> module._c._create_method_from_trace(method_name, func, example_inputs, var_lookup_fn, _force_outplace)

Unfortunately this message doesn't help, as I'm under the impression that all the layers in my modules already have tensors or tuples output. Even worse the error message doesn't tell me which layer is the culprit.
What is the recommended way to ask pytorch JIT to explain it? I already enabled PYTORCH_JIT=0.
I'm using pytorch 1.3.0 with only CPU support

cv2.imshow() starts without poping up a window when called in threading

cv2.imshow() do not pop up the window when called in the threading. An icon of python3 appears in the docker, but no window, no plot. Besides, I need the function of half-duplex communication, thus I cannot just remove threading. How can I correctly show the picture inside threading? Any response is appreciated.
Background: MacOS Catalina, python==3.5, opencv==3.4.2
import cv2
import threading
def run():
# start the camera
video_reader = cv2.VideoCapture(0)
while True:
# collect image
ret_val, image = video_reader.read()
cv2.imshow('image', image)
if cv2.waitKey(1) == 27:
break # esc to quit
t = threading.Thread(target=run, name="run")
t.start()

UIAlertController crashes when running under XCode 6.1 debugger

// create an action sheet
UIAlertController *view= [UIAlertController

}];
UIAlertAction* no = [UIAlertAction

{
//Do some thing here
[view dismissViewControllerAnimated:YES completion:nil];
}];
[view addAction:yes];
[view addAction:no];
view.popoverPresentationController.sourceView = self.view;
view.popoverPresentationController.sourceRect = CGRectMake(self.view.bounds.size.width / 2.0, self.view.bounds.size.height / 2.0, 1.0, 1.0);

I have restarted the Mac, but it still happens. Any idea what's causing this?

Why would app try to save to PLSharedManagedObjectContext?

The following is a crash report I received from my crash reporting service, HockeyApp. The reason for the failure is a failure to save in PLSharedManagedObjectContext. I (think) I am doing all of my saves in the main app delegate managedObjectContext. Why is the PLSharedManagedObjectContext the one being saved to?
I think this is the relevant code:
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
__ENTERING_METHOD__
DLog(#"info:%#",info);
NSURL *assetURL = [info objectForKey:UIImagePickerControllerReferenceURL];
__block UIImage *originalImage = [info objectForKey:UIImagePickerControllerOriginalImage];
CGSize cropSize = CGSizeMake(320,320);
CGFloat previewWindowHeight = 100.0f;
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
__block UIImage *previewImage;
if (originalImage) {
DLog(#"WE DO HAVE AN ORIGINAL IMAGE");
}
else {
DLog(#"WE DO NOT HAVE AN ORIGINAL IMAGE");
}
ImageEditor *imageEditor = [[ImageEditor alloc] initWithNibName:nil bundle:nil];
[imageEditor setRotateEnabled:NO];
[imageEditor setCheckBounds:NO];
[imageEditor setSourceImage:originalImage];
[imageEditor setPreviewHeight1:[NSNumber numberWithDouble:previewWindowHeight]];
[imageEditor setCropSize:cropSize];
imageEditor.doneCallback = ^(UIImage *editedImage, UIImage *originalImageMax1024, BOOL canceled){
picker.delegate = nil;
if(!canceled) {
if (editedImage) {
UIImage *scaledThumbnail = [HFImageEditorViewController getThumbnailForImage:editedImage size:CGSizeMake(PERSON_THUMBNAIL_SIZE,PERSON_THUMBNAIL_SIZE) round:PERSON_THUMBNAIL_ROUND];
[self setObjectCroppedImage:editedImage thumbnail:scaledThumbnail updateHeaderView:YES mocSave:NO];
[self setObjectMainImage:originalImageMax1024 mocSave:NO];
[Helper mocSave];
self.imageToShow = originalImage;
}
}
[Helper controller:self dismissControllerModal:YES];
};
[library assetForURL:assetURL resultBlock:^(ALAsset *asset) {
if (!originalImage) {
originalImage = [UIImage imageWithCGImage:[[asset defaultRepresentation] fullResolutionImage]];
}
[imageEditor setSourceImage:originalImage];
previewImage = [UIImage imageWithCGImage:[asset aspectRatioThumbnail]];
[imageEditor setPreviewImage:previewImage];
[imageEditor reset:NO];
//DLog(#"originalImage.imageOrientation:%d",originalImage.imageOrientation);
[picker pushViewController:imageEditor animated:YES];
} failureBlock:^(NSError *error) {
DLog(#"Failed to get asset from library");
if (originalImage) {
[imageEditor setSourceImage:originalImage];
[imageEditor setPreviewImage:nil];
[imageEditor reset:NO];
[picker pushViewController:imageEditor animated:YES];
}
else {
[Helper showSimpleAlertWithTitle:NSLocalizedString(#"Image Could Not Be Set", #"Image Could Not Be Set") message:NSLocalizedString(#"Failed to retrieve selected image asset from the Library.", #"Failed to retrieve selected image asset from the Library.")];
[Helper controller:self dismissControllerModal:YES];
}
}];
}

PLSharedManagedObjectContext appears to be an undocumented class that's part of PhotoLibraryServices.framework. That framework is itself undocumented, but the fact that it shows up in your backtrace implicates it.
As a result I don't think that this exception has anything really to do with your Core Data code. PhotoLibraryServices is using Core Data internally somewhere, and failing to do so. This might mean that you're doing something wrong with your photo handling, or it might be a framework bug. Either way, looking at your own Core Data code will almost certainly miss the point.
Having said that, there's also an indication that a performBlock call might have been involved somehow. Depending on what your mocSave method does, there might be a connection.

uiwebview webthread crashing

My App with an UIWebView is crashing a lot. The crash is often slightly different, but it's always a crash of the "WebThread" with a similar stack trace.
I found this question but I don't think it's my case, I have iOS 6 and I'm not loading Office documents.
I'm using websocket to send messages to a server and using ajax commet to receive messages from a server.
The crashes always happen when I'm starting that connections.
