Question

我试图运行这段代码(https://github.com/ryanwhalen/patentsview_data_download/blob/master/patentsview_download.py)，并得到以下错误：

Traceback (most recent call last):
  File "...\patentsview_data_download-master\221113\patentsview_download_221113.py", line 285, in <module>
    download_and_parse_tsv(url)

    os.remove(os.getcwd()+'/'+cleaned_file)                       
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: '...\patentsview_data_download-master\\221113/g_applicant_not_disambiguated.tsv2'

有人能让我知道怎样才能纠正错误吗？谢谢。

我期待运行这段代码并下载专利数据集。

这是因为在第142行，中间文件被打开，但从未关闭。这句话是：

infile = open(os.getcwd()+'/'+cleaned_file, 'r', encoding = 'utf-8')

我建议这样改写：

with open(os.getcwd()+'/'+cleaned_file, 'r', encoding = 'utf-8') as infile:
    # here goes the rest of file processing
