我的目录在这段代码中应该是什么？

https://github.com/nicolas-gervais/predicting-car-price-from-scraped-data/tree/master/picture-scraper

我正在尝试在 google colab 上运行 main.py 文件，但由于我放置的目录而出现错误。我已将路径作为包含 .py 文件的文件夹。我已将该目录作为包含图像的文件夹，但我收到此错误。

python3: can't open file '/content/gdrive/My': [Errno 2] No such file or directory 

代码：

import os

path = '/content/gdrive/My Drive/picture-scraper' #Where the .py files are located

os.chdir(path)

directory = '/content/gdrive/My Drive/Car Dataset' #Where the images are located

files = ['scrape', 'tag', 'save', 'select']

if __name__ == '__main__':
if not os.path.isdir(directory):
    os.mkdir(directory)

[os.system('python ' + path + f'{file}.py ' + directory) for file in files]

Answer 1

不要将其用作循环：

[os.system('python ' + path + f'{file}.py ' + directory) for file in files]

改用这个：

for file in files:
    command = f'python {path}{file}.py {directory}'
    print('Running command:', command)  # for debugging purposes
    os.system(command)

当你这样做时，我怀疑你会看到这个输出：

Running command: python /content/gdrive/My Drive/picture-scraperscrape.py /content/gdrive/My Drive/Car Dataset
Running command: python /content/gdrive/My Drive/picture-scrapertag.py /content/gdrive/My Drive/Car Dataset
Running command: python /content/gdrive/My Drive/picture-scrapersave.py /content/gdrive/My Drive/Car Dataset
Running command: python /content/gdrive/My Drive/picture-scraperselect.py /content/gdrive/My Drive/Car Dataset

而且我怀疑如果您将这些命令复制并粘贴到命令行中，那么这些命令都不起作用。事实上，您可能会遇到之前看到的错误，即：

python3: can't open file '/content/gdrive/My': [Errno 2] No such file or directory 

要使它们起作用，请更改此行：

command = f'python {path}{file}.py {directory}'

到：

command = f'python "{path}/{file}.py" "{directory}"'

然后你会看到这个输出：

Running command: python "/content/gdrive/My Drive/picture-scraper/scrape.py" "/content/gdrive/My Drive/Car Dataset"
Running command: python "/content/gdrive/My Drive/picture-scraper/tag.py" "/content/gdrive/My Drive/Car Dataset"
Running command: python "/content/gdrive/My Drive/picture-scraper/save.py" "/content/gdrive/My Drive/Car Dataset"
Running command: python "/content/gdrive/My Drive/picture-scraper/select.py" "/content/gdrive/My Drive/Car Dataset"

现在，如果您将这些命令复制并粘贴到终端中，它们应该可以工作。 （事实上​​，这些命令应该已经在运行，所以您甚至不必复制粘贴它们来测试它们。）

（我承认，我没有测试过这个输出。）

如果它确实有效，您可以删除调试行。

我希望这会有所帮助！
