无法将 csv 文件导入协作？

Question

我是 python 的新手，一直在尝试将 csv 文件放到 google 协作笔记本上。我不确定我做错了什么。已经尝试使用“/”，但它们也不起作用。

import pandas as pd
testData = pd.read_csv(r'C:\Users\User\Documents\ml\training.csv')

我收到多个错误：


FileNotFoundError                         Traceback (most recent call last)
<ipython-input-37-d77976d861ee> in <module>()

Colab 无法从您的本地设备读取文件，它运行在云服务器上，无法访问您的本地文件系统。您需要上传文件。有多种方法可以实现此目的，请查找最适合您需求的方法。

提示您上传文件的示例，然后您可以将其读入您的笔记本。

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


df = pd.read_csv(io.BytesIO(uploaded['filename.csv']))
