如何在colab中解压缩图像文件夹

Question

I want to train a deep learning model on a Devanagari dataset containing around 9000 images. Since the dataset is huge, I want to use Google colab since it's GPU supported.I uploaded folder from my local machine to Colab in Zip format . But an error is occurred while unzipping file.

    from google.colab import files

uploaded = files.upload()

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

When I tried following to unzip file

unzip devanagari-character-dataset.zip  

I have following error.

      File "<ipython-input-8-92b289004693>", line 1
        unzip devanagari-character-dataset.zip
                       ^

SyntaxError: invalid syntax

How to solve above issue.

Answer 1

import zipfile
with zipfile.ZipFile(path_to_zip_file, 'r') as zip_ref:
    zip_ref.extractall(directory_to_extract_to)

Answer 2

Assuming python for that part

unzip "devanagari-character-dataset.zip" 

not

unzip devanagari-character-dataset.zip   

Perhaps wrap it in quotes if you want it to be serviced by things installed with pip (then see @Vaibhav's answer)

OR: possibly precede it with a ! to make it a command (if you want the backend to service it like a regular command line serviced by things installed with apt)

like

!unzip devanagari-character-dataset.zip
