如何在Google Colab上打开txt？

Question

我的 iris.txt 存储在我的 Google Drive 的 My Drive/ML 中，我试图打开并阅读它。

import csv
import numpy

file = open(r"/drive/ML/iris.txt")
mylist = list(csv.reader(file))
lines = numpy.asarray(mylist)

它返回给我错误，我该怎么办？

      9 mylist = list(csv.reader(file))
     10 lines = numpy.asarray(mylist)

IOError: [Errno 2] No such file or directory: '/my drive/ML/iris.txt'

Answer 1

使用这个：

from `google.colab` import files

uploaded = files.upload()

import io

df2 = pd.read_csv(io.BytesIO(uploaded['ex1data1.csv']))

Answer 2

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

for f in uploaded.keys():
    file = open(f, 'r')
    lines = file.readlines()
