mac os는 어떤식으로 설정해야 하나요? 궁금해서 여쭤봅니다

안녕하세요 영상 시청 도중 불편한 것 있어 질문 드립니다. 가운데 아래에 있는 보안프로젝트 베너광고 때문인데요. 없앨 수는 없나요?

강의해주신 내용과 같이 코딩을 했는데, 마우스 버튼을 눌렀다가 떼었을 때 세로 방향으로 돌지 않습니다.  단계별로 state가 넘어가는지 확인하기 위해 디버그.로그 코드를 넣어 놓았습니다.  제가 무엇을 잘못해서 동작하지 않는 것일까요? 답변 부탁드립니다. using System.Collections; using System.Collections.Generic; using UnityEngine; public class ShooterRotator : MonoBehaviour { private enum RotateState { Idle,Vertical,Horizontal,Ready } private RotateState state = RotateState.Idle; public float verticalRoteteSpeed = 360f; public float horizontalRoteteSpeed = 360f; // Start is called before the first frame update void Start() { } // Update is called once per frame void Update() { if(state == RotateState.Idle) { if(Input.GetButtonDown("Fire1")) { state = RotateState.Horizontal; } } else if(state == RotateState.Horizontal) { if(Input.GetButton("Fire1")) { transform.Rotate(new Vector3(0,horizontalRoteteSpeed * Time.deltaTime,0)); } else if(Input.GetButtonUp("Fire1")) { state = RotateState.Vertical; Debug.Log("1"); } else if(state == RotateState.Vertical) { if(Input.GetButton("Fire1")) { transform.Rotate(new Vector3(-verticalRoteteSpeed * Time.deltaTime,0,0)); Debug.Log("2"); } else if(Input.GetButtonUp("Fire1")) { state = RotateState.Ready; Debug.Log("3"); } } } } }

배열 인덱스안에 -1이 들어가면 안되니까 concat으로 처리해주셨는데 왜 [][칸] 은 영향을 주지 않나요? 0,0을 누르면 칸도 -1이 되는거 아닌가요 강사님?

4.4 Random Forest에서 아래 코드를 입력하면 File b'./human_activity/features.txt' does not exist: b'./human_activity/features.txt'에러가 나오는데요...왜 이런건지 궁금합니다.import pandas as pd def get_human_dataset( ): # 각 데이터 파일들은 공백으로 분리되어 있으므로 read_csv에서 공백 문자를 sep으로 할당. feature_name_df = pd.read_csv('./human_activity/features.txt',sep='\s+', header=None,names=['column_index','column_name']) # 중복된 feature명을 새롭게 수정하는 get_new_feature_name_df()를 이용하여 새로운 feature명 DataFrame생성. new_feature_name_df = get_new_feature_name_df(feature_name_df) # DataFrame에 피처명을 컬럼으로 부여하기 위해 리스트 객체로 다시 변환 feature_name = new_feature_name_df.iloc[:, 1].values.tolist() # 학습 피처 데이터 셋과 테스트 피처 데이터을 DataFrame으로 로딩. 컬럼명은 feature_name 적용 X_train = pd.read_csv('./human_activity/train/X_train.txt',sep='\s+', names=feature_name ) X_test = pd.read_csv('./human_activity/test/X_test.txt',sep='\s+', names=feature_name) # 학습 레이블과 테스트 레이블 데이터을 DataFrame으로 로딩하고 컬럼명은 action으로 부여 y_train = pd.read_csv('./human_activity/train/y_train.txt',sep='\s+',header=None,names=['action']) y_test = pd.read_csv('./human_activity/test/y_test.txt',sep='\s+',header=None,names=['action']) # 로드된 학습/테스트용 DataFrame을 모두 반환 return X_train, X_test, y_train, y_test X_train, X_test, y_train, y_test = get_human_dataset()

왜 그런건가요?

안녕하세요, 정말 좋은 강의 잘 듣고 있습니다!! sklearn 의 클래스를 사용하다보면 fit, transform이 많이 언급되는데요. 어쩔때는 fit 하고나서 transform을 수행하거나 fit_transform으로 한번에 수행하는 경우가 있는데 두 가지의 명확한 차이가 무엇일까요? 아래의 PCA 코드로 테스트해보니까 반환되는 결과값이 소수점에서 아주 미세하게 차이가 나긴하더라구요. from sklearn.preprocessing import StandardScaler iris_scaled = StandardScaler().fit_transform(irisDF.iloc[:, :-1]) from sklearn.decomposition import PCA pca = PCA(n_components=2) #fit( )과 transform( ) 을 호출하여 PCA 변환 데이터 반환 pca.fit(iris_scaled) iris_pca = pca.transform(iris_scaled) print(iris_pca.shape) # fit_transform imp = pca.fit_transform(iris_scaled) imp[0,0] - iris_pca[0,0] >> -3.552713678800501e-15

inflearn에 올려져있는 Makefile 파일을가상머신에서 어떻게 다운로드받아서 사용하나요?

동영상 강의를 들을 때 어떤 방식으로 배우는 게 좋을까요? 지금은 노트에 적으면서 배우고 있습니다. 그래서 필기하면서 영상 보다보니 영상 내용보다 많이 오래 걸리네요. 어느 방식이 배우는데 있어서 좋을지 궁금합니다.

일단 이것도 뭔가를 계산해주니 함수같기는 한데 보통 예를들어 if (word[length(word)-1])저런 식의 형태였다면 헷갈리지 않을 것 같은데 저런식의 함수를 따로 부르는 명칭이 있나요? 변수종속함수?

여기서 [env] 처럼 뒤에 배열이 붙는경우는 어떻게 해석하야하나요?

사전지식은 무엇이 필요한가요?

안녕하세요 선생님! 파이어스토어에서 저장한 게시물을 가져와서 searchpage에 보여주는 것을 하고있는데요..! 이런 에러와 함께 화면 사진 부분에 에러가뜹니다. 찾아봐도 어떻게 고쳐야하는 에러인기 잘 모르겠어서 질문 드립니다ㅠㅠ

좋은강의 감사합니다. 다른게아니라 잘따라하다가 save가 안되서 질문 드려요 console 로 다찍어봤는데 video 객체까지 다 가져오는데 save 함수가 안되네요.. 왜이런걸까요? 아무런 오류도 나오지 않습니다. 

뭐가 문제인지 잘 모르겟습니다 흑흑

안녕하세요 기선님 강의를 보다가 제가 기존에 배운것과 혼동되는 부분이 있어서 이렇게 질문 올립니다. 제가 기존에 알던 MVC에서의 Model은 데이터, 로직 및 규칙을 직접 관리하는 컴포넌트로 알고있으며 위키 백과에도 그렇게 정의되어 있습니다. 아마 이것을 코드로 보면 비즈니스 로직을 처리하는 ` @Service`일것입니다. 기선님께서 수업 자료에 올리신 모델의 정의 `도메인 객체 또는 DTO로 화면에 전달할 또는 화면에서 전달 받은 데이터를 담고 있는 객체.`는 제가 알던 모델이 아닌거같습니다.... 기존의 제가 이해한 개념과는 많이 다른거 같은데 어느쪽으로 이해해야할까요? 참조한 문서 * 위키 백과 MVC Pattern: https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller * 미디엄:  https://medium.com/@jang.wangsu/%EB%94%94%EC%9E%90%EC%9D%B8%ED%8C%A8%ED%84%B4-mvc-%ED%8C%A8%ED%84%B4%EC%9D%B4%EB%9E%80-1d74fac6e256
