Question

我正在运行以下代码以及其他一些代码，但我正面临着与此部分有关的一些问题。

idx_to_movie = {}
with open('u.item', encoding = "ISO-8859-1") as f:
    for line in f.readlines():
        info = line.split('|')
        idx_to_movie[int(info[0])-1] = info[4]

def top_k_movies(similarity, mapper, movie_idx, k=6):
    return [mapper[x] for x in np.argsort(similarity[movie_idx,:])[:-k-1:-1]]

idx = 0 # Toy Story
movies = top_k_movies(item_similarity, idx_to_movie, idx)
posters = tuple(Image(url=get_poster(movie, base_url)) for movie in movies)

KeyError Traceback（最近一次调用最后一次）

 <ipython-input-78-17abeb8d67ed> in 
 get_poster(imdb_url, base_url)

尝试： file_path = json.loads（response.text）['posters'] [0] ['file_path'] 不同的是：

KeyError：'海报'

在处理上述异常期间，发生了另一个异常：

IndexError Traceback（最近一次调用最后一次）

 <ipython-input-85-a456f8efd408> in <module>()
 idx = 0 # Toy Story   
 movies = top_k_movies(item_similarity, idx_to_movie, idx)
 posters = tuple(Image(url=get_poster(movie, base_url)) for movie in movies)

<ipython-input-85-a456f8efd408> in <genexpr>(.0)
idx = 0 # Toy Story
movies = top_k_movies(item_similarity, idx_to_movie, idx)
posters = tuple(Image(url=get_poster(movie, base_url)) for movie in movies)

in

  get_poster(imdb_url, base_url)
  payload['query'] = movie_title
  response = requests.get('http://api.themoviedb.org/3/search/movie', params=payload, headers=headers)
  movie_id = json.loads(response.text)['results'][0]['id']
  payload.pop('query', None)
  movie_url = 'http://api.themoviedb.org/3/movie/{:}/images'.format(movie_id)

IndexError：列表索引超出范围
