如何在Google colab中访问上传的文件

我是 python 新手，我使用Google Colab。我上传了一个train_data.npy进入google Colab，然后我想使用它。根据这个链接如何在 Google Colaboratory 中导入并读取 shelve 或 Numpy 文件？ https://stackoverflow.com/questions/47212852/how-to-import-and-read-a-shelve-or-numpy-file-in-google-colaboratory

当我运行我的代码时，我遇到这个错误：

类型错误：“dict_keys”对象不支持索引

这是我的代码：

uploaded = files.upload()

for fn in uploaded.keys():
  print('User uploaded file "{name}" with length {length} bytes'.format(
      name=fn, length=len(uploaded[fn])))

with open('train_data.npy', 'w') as f:
f.write(uploaded[uploaded.keys()[0]])

Thanks

这是对您的代码片段的调整，它将使用上传的文件名将所有上传的文件保存在当前目录中。

from google.colab import files
uploaded = files.upload()

for name, data in uploaded.items():
  with open(name, 'wb') as f:
    f.write(data)
    print ('saved file', name)
