FileNotFoundError：[Errno 2] 没有这样的文件或目录：'corpus_or_AB_FMC.xlsx'

Question

我有一个包含很多 excel 文件的目录。我的目标是阅读所有这些 excel 文件并从中提取一些信息。我使用下面的脚本来读取目录，但仍然出现错误。文件已被识别，但代码告诉它没有创建它们，这很奇怪，因为有一行打印文件的名称。但是用pandas读取文件时，是不成立的。

/home/geta/kelo/eXP/Test/corpus
-----File in processed : corpus_or_AB_FMC.xlsx

这里是代码：

dir = "/home/geta/kelo/eXP/Test/corpus"
for root, subdirs, files in os.walk(dir):
    print(root)
    for file in files:
        #print(files)
        print("-----File in processed :", file)
        # -----File in processed : corpus_or_AB_FMC.xlsx  # this file si located in the corpus directory
        sentences = pd.read_excel(file, sheet_name= 0)
        data_id = sentences.identifiant
        print("Total phrases: ", len(data_id))
        data = sentences.verbatim

        data_label = sentences.etiquette
        #print(type(data_id))
        #print(type(data))
        #number = LabelEncoder()
        # 0 = C; 1= F; 2= M
        #data_label = number.fit_transform(sentences.etiquette.astype('str'))
        #print(data_label)
        
        print("etiquette  :" , sentences['etiquette'].unique())
        classes = sentences['etiquette'].unique()
        len_classes = len(classes)

Answer 1

file 是一个文件名，不包括它的路径。使用os.path.join：

sentences = pd.read_excel(os.path.join(root, file), sheet_name=0)

加入文件名及其绝对路径。
