How to fix zipfile read error in Colaboratory?

Question

While extracting zipfile in to my google drive using colaboratory, I got an error saying zipfile read error. How to fix it?

I'm trying to unzip file using the following python 3 script:

from google.colab import drive
drive.mount('/gdrive')

!unzip '/gdrive/My Drive/file.zip' -d '/gdrive/My Drive/Destination/'

After extracting 4 files from the zip I got this error

error:  zipfile read error

Answer 1

I was unable to resolve the why, but was able to get put a band-aid on the problem (along with some process informatin) with the following Python code:

from zipfile import ZipFile

# Get information about how much you're decompressing
zf = ZipFile('./gdrive/My Drive/poizon/data/images.zip')
uncompress_size = sum((file.file_size for file in zf.infolist()))
print('uncompressed_size',uncompress_size/1e6)

# Loop through all files attempting to decompress each individually
extracted_size = 0
for file in zf.infolist():
    extracted_size += file.file_size
    print ("%s %%" % (extracted_size * 100/uncompress_size))
    try:
      zf.extract(file)
    except:
      continue

Answer 2

Try this:

import zipfile
import os

file_location = 'file_path/file_name.zip'

with zipfile.ZipFile(file_location, 'r') as zip_ref:
    zip_ref.extractall('/content') # Replace '/content' with where you want to extract all files.

I hope it will not show any error.
