Have you already pre-compiled the model?

The omz code compiles the model before using it.

cvp

For each character, the compiled model is generated as
file:///private/var/mobile/Containers/Data/Application/C285FD04-6489-45E5-A6C5-D4A44D300BBC/tmp/(A%20Document%20Being%20Saved%20By%20Pythonista3%20643)/OCR.mlmodelc/

Omz code needs to be improved so this compilation is done only once, not for each character...

It might be a good idea to compile it once, copy it to a regular location, then delete the tmp file. That's what Apple recommends

If you run the code that does a fresh compile every time, you will quickly fill up the tmp storage. I'm not how reliable the cleaning of tmp files is.

pavlinb

Agree. .

cvp

Set vn_model global,
call load_model at begin of main and
remove load_model in _classify_image_data

Script is quicker and does not generate a compiled model at each character

cvp

After run, tmp folder is empty

cvp

def load_model():
	global vn_model
	
def _classify_img_data(img_data):
	global vn_model
	'''The main image classification method, used by `classify_image` (for camera images) and `classify_asset` (for photo library assets).'''
	#vn_model = load_model()
	
def main():
    global vn_model
    vn_model = load_model()

After some tests with small texts, Pythonista storage has increased of 1GB but I hope this will decrease in some hours...

cvp

import os
d = '/private/var/mobile/Containers/Data/Application/C285FD04-6489-45E5-A6C5-D4A44D300BBC/tmp/'
os.chdir(d)
l = os.listdir()
for e in l:
	print(e)

Shows ....a lot of

(A Document Being Saved By Pythonista3 628)
(A Document Being Saved By Pythonista3 563)
(A Document Being Saved By Pythonista3 54)

cvp

Trying to remove it gives

PermissionError: [Errno 1] Operation not permitted: '(A Document Being Saved By Pythonista3 92)'

cvp

Each file has a size of 96 bytes??????????

pavlinb

Works.

No more crashes with complex images.

cvp

Shame on me, each line is a folder, that's why it is 96 bytes and unremovable 😢 because not empty

cvp

The .mlmodelc are not permitted for removal...

cvp

.mlmodelc is still a folder, one more time, shame on me...
1GB of temp files...

cvp

In the text detection script, add

	print(c_model_url)

Note the code d = '/private/var/mobile/Containers/Data/Application/C285FD04-6489-45E5-A6C5-D4A44D300BBC/tmp/'
Replace it in the little script here-under to clean /tmp folder

import os

n = 0
s = 0
def loc_dirs(path):
		global n,s
		try:
			file_path = path
			os.chdir(file_path)
			filelist = os.listdir(file_path)
			for file in filelist:
				print(file)				
				f_full = file_path + file
				if os.path.isdir(f_full):
					loc_dirs(path+file+'/') # explore it
				else:	

					loc_size = os.path.getsize(f_full)
					n = n + 1
					s = s + loc_size
					os.remove(f_full)
			os.rmdir(file_path)
		except Exception as e:
			print('exception: ',e)
		return


d = '/private/var/mobile/Containers/Data/Application/C285FD04-6489-45E5-A6C5-D4A44D300BBC/tmp/'
#loc_dirs(d)
print(n,s)

@pavlinb 20GB?

pavlinb

May be 2GB.

cvp

@pavlinb 2.027.261.814 = 2GB, Sorry for my old eyes 😢
