python - Issues with pyinstaller and reportlab -

-

alright have python project want compile, decided use pyinstaller (first time compiling python). compiled fine when run exe returns -1. after bit of messing around figured out related reportlab.platypus.

so first instinct check see if using hooks changed anything, tried adding reportlab.pdfbase._fontdata , reportlab.lib.utils hooks (these hook files find related reportlab). despite effort still failed.

here output when exe run terminal:

traceback (most recent call last):   file "<string>", line 12, in <module>   file "<frozen importlib._bootstrap>", line 969, in _find_and_load   file "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked   file "<frozen importlib._bootstrap>", line 664, in _load_unlocked   file "<frozen importlib._bootstrap>", line 634, in _load_backward_compatible   file "c:\users\jon\desktop\pyinstaller-3.1.1\pyinstaller\loader\pyimod03_importers.py", line 389, in load_module     exec(bytecode, module.__dict__)   file "board_builder.py", line 5, in <module>   file "<frozen importlib._bootstrap>", line 969, in _find_and_load   file "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked   file "<frozen importlib._bootstrap>", line 664, in _load_unlocked   file "<frozen importlib._bootstrap>", line 634, in _load_backward_compatible   file "c:\users\jon\desktop\pyinstaller-3.1.1\pyinstaller\loader\pyimod03_importers.py", line 389, in load_module     exec(bytecode, module.__dict__)   file "site-packages\reportlab\platypus\__init__.py", line 7, in <module>   file "<frozen importlib._bootstrap>", line 969, in _find_and_load   file "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked   file "<frozen importlib._bootstrap>", line 664, in _load_unlocked   file "<frozen importlib._bootstrap>", line 634, in _load_backward_compatible   file "c:\users\jon\desktop\pyinstaller-3.1.1\pyinstaller\loader\pyimod03_importers.py", line 389, in load_module     exec(bytecode, module.__dict__)   file "site-packages\reportlab\platypus\flowables.py", line 32, in <module>   file "<frozen importlib._bootstrap>", line 969, in _find_and_load   file "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked   file "<frozen importlib._bootstrap>", line 664, in _load_unlocked   file "<frozen importlib._bootstrap>", line 634, in _load_backward_compatible   file "c:\users\jon\desktop\pyinstaller-3.1.1\pyinstaller\loader\pyimod03_importers.py", line 389, in load_module     exec(bytecode, module.__dict__)   file "site-packages\reportlab\lib\styles.py", line 28, in <module>   file "<frozen importlib._bootstrap>", line 969, in _find_and_load   file "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked   file "<frozen importlib._bootstrap>", line 664, in _load_unlocked   file "<frozen importlib._bootstrap>", line 634, in _load_backward_compatible   file "c:\users\jon\desktop\pyinstaller-3.1.1\pyinstaller\loader\pyimod03_importers.py", line 389, in load_module     exec(bytecode, module.__dict__)   file "site-packages\reportlab\rl_config.py", line 131, in <module>   file "site-packages\reportlab\rl_config.py", line 102, in _startup   file "site-packages\reportlab\lib\utils.py", line 695, in rl_isdir attributeerror: 'frozenimporter' object has no attribute '_files' main returned -1

from gather crashes on running line 5 in "board_builder.py" (the file handles reportlab in project) here first 5 lines of file:

import subprocess import datetime reportlab.lib.units import mm, inch reportlab.lib.pagesizes import legal, landscape reportlab.platypus import simpledoctemplate, table

i have no idea attributeerror throwing means, advice welcome!

well got working,

decided go @ attributeerror being thrown inspected reportlab/rl_config.py , reportlab/lib/utils.py files , found checking objects recursively looking directories (as insinuated rl_isdir). how frozenimporter got stuck being checked list of other objects

so replaced line:

return len(list(filter(lambda x,pn=pn: x.startswith(pn),list(__loader__._files.keys()))))>0

with:

try:     return len(list(filter(lambda x,pn=pn: x.startswith(pn),list(__loader__._files.keys()))))>0 except attributeerror:     return false

this may not have been cleanest efficient way resolve issue touches 1 line of original code found straight forward solution.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
