안녕하세요. callable 함수를 사용하면서 str에 __call__ attribute가 있는지 확인해봤습니다. ['__add__', '__class__', '__contains__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'capitalize', 'casefold', 'center', 'count', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'format_map', 'index', 'isalnum', 'isalpha', 'isascii', 'isdecimal', 'isdigit', 'isidentifier', 'islower', 'isnumeric', 'isprintable', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans', 'partition', 'removeprefix', 'removesuffix', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill']               callable에서는 true인데 dir에서 __call__을 찾을 수 없는 이유를 알 수 있을까요?

안녕하세요. 강의 잘 듣고 있습니다.  MMDetection의 Data Pipeline 중에서  Normalization 할때, Mean, Std는  train dataset 전체에 대해서 Mean과 STD를 구하는 거죠?  (Test dataset은 제외하고 구하는 거죠?) 그리고 Augmentation 은 Train_pipe_line에 적용된다고 생각하면 되는 거죠?   

사전에 마리아디비를 설치하고 해야하나요?

초보적인 질문일 수 있지만 궁금한 부분이 있어 문의 드립니다.   강의 내용 중 " 세션과 관련된 쿠키( JSESSIONID)를 탈취 당했을 경우 오랜 시간이 지나도 해당 쿠키로 악의적인 요청을 할수있다. " 라는 내용이 있고, 세션 타임아웃 설정으로 방지하는 것으로 이해하였습니다.   그런데 탈취 당하여 악용하는 시점에, 타임아웃으로 설정한 30분이 지나지 않았다면 이 순간에는 악용이 가능하지 않나 생각이 들었습니다.   이 순간에는 막을 수 있는 방법이 따로 있는 것일까요 ?

안녕하세요ㅎ-ㅎ! 차분한 강의를 즐겁게 수강하고 있는 수강생입니다! 자바스크립트를 배운지 얼마안되서 궁금한게 많은데용..   5:00쯤에 Hello의 리턴값에 중괄호를 넣으면 결과값이 안나오는 이유는 무엇인가요?.? const Hello = (data) => { <h1>Hello, Component {data.name}</h1> }; 이렇게 작성하면 값이 안 나오더라고요...!!   화살표 함수에서 리턴에 중괄호 삭제는 옵션 아닌가요?.? ..제 코드가 오타가 있는건지 ;-; .. 잘못알고 있는 내용이 있을까요!!?   도와주세요~      

집값 예측 강의에서 보스턴 자료가 더이상 파이토치에서 지원하지 않는다고 합니다.   초보분들을 위해서 다른 데이터로 변경한 강의가 제공된다면, 더 좋은 강의가 될 것 같습니다. (또는 이전 보스턴 자료를 받는 다른 방법을 이용하고 윤리적인 이슈로 스터디 용도로만 사용할 것을 명시)

안녕하세요! 지금까지 제가 개발해보면서 Layer 보단 Tag를 사용해서 물체를 감지하는 방식을 썼었는데 혹시 여기서 성능 차이가 발생하나요? Tag보단 Layer과 비트연산자를 사용하는 방식이 더 좋을까요?   아 그리고 Tag는 비트연산자를 사용할 수 없나요?

To give you a better picture, below is a list of common reasons why your Cash App transfer failed. An Outdated Cash App Account It might sound strange and also something very simple but yes.

To find out whether this is the problem, do ensure that you update your app and keep doing so with the new updates. Not Having Enough Balance While updating your app is the first point listed in this post, ideally, you should first confirm your account balance. Sometimes the “Cash App transfer failed” or “Cash App transfer pending” message might pop up even though money was deducted from your account. In other words, the transaction went through. Terrible Internet Connection Speed If you are working with a slow WIFI connection, or simply one that comes and goes chances are your Cash App transfer will fail. For a transaction to go through on Cash App, you not only need a fast internet connection but one that is very stable.  Tips To Avoid Cash App Transfer Failed Issue   The Cash App is one of the best money transfer apps. You can transfer money from one bank account to another within a minute.   Most of the time Cash App works great as it should work but sometimes due to some network dropouts or other issues, you might face a “Transaction Failed” error. In this article, we will discuss how to fix this Cash App transfer failed issue.   Change Your Phone’s Date And Time Settings One of the most common reasons behind this Cash App transfer failed error is the incorrect date and time settings. It’s simple and easy to fix. Just follow the steps below: #Go To Setting->Date and Time->Select Automatic Date and Time option from the menu. Now, select the Set Automatically toggle the option on. Next, change the time zone of your phone to some other city. Now, you can open the Cash App and try transferring money again. If the performance is still not as expected then proceed further. Clear Cache & Data Of The App Sometimes clearing the cache and data of the Cash App fixes this issue. Just follow these steps: Go To Setting->Apps->Cash App and select Storage and Clear Cache and Clear Data. Now, open the Cash App again and try transferring money again. If performance is still not as expected then proceed again to the next method. If you are getting this Cash App transfer failed error, then you might want to check your date and time settings on your Android phone.   Uninstall & Re-install The App If the above steps don’t work for you then try uninstalling and re-installing the Cash App and check if that helps. To uninstall: Go to Settings->Apps and find your Cash App in the list of apps->click on it and select the ‘Uninstall’ button. To re-install: Search for Cash App in App Store or Play Store and install it. If none of the above methods work, then you may want to reach out to Cash App Support for additional help getting up & running.   Check Your Internet Connection If you can’t make a transfer via your mobile data and Wi-Fi, then the app won’t allow you to make this transfer. Make sure that before transferring money or making any payments, both your mobile data and WiFi connection is working fine.   Restart Your Device If you are getting this Cash App transfer failed error, then restarting your device can also help. Just press and hold the Power button until the menu options appear->select the Restart option to restart your phone. Now try transferring money using Cash App again. If still, performance is not as expected then proceed further.   Update Cash App to the Latest Version  If you are getting this error, it’s possible that either your Cash App has an older version or the issue is with servers. To fix this problem, update the Cash App on both devices to the latest version available in the App Store or Play Store.   Contact Customer Service for Help If you are unable to fix the Cash App transfer failed issue yourself, then it’s time to get help from their support team. First, open up the app. Select “I have a problem with Cash App” at the bottom of the page->click on Chat or Call under that section.

하,,, 하라는대로 똑같이 했는데 왜 안되는걸까요, ㅜㅜㅜㅜ

STL이 너무 편해서  거의 맵이랑 벡터만으로 문제를 풀고 있는데요 이러면 감점요소인가요? 그리고 막 sort, reverse, acumulate 등등 라이브러리 쓰지 않고 직접 구현해서 쓰면 가산점 주고 그러나요?

테마와 폰트가 눈에 잘 띄고 예뻐요 ! 정보좀요.. ㅋㅋ
