Install dependencies from requirements.txt in Google Colaboratory

Question

How to install python dependencies using a requirements file in Google Colab?

Like the equivalent of pip install -r requirements.txt

Answer 1

With Daniel's hint above, I was able to solve it.

Using the "uploading files from local computer script" I uploaded my requirements.txt file onto Google Colab platform. Script is found here. This is the script,

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])))

The output on executing, clearly says that, it is saving this file as 'requirements.txt'. I couldn't however find this file in Google Drive, which is fine by me. Then,

!pip install -r requirements.txt

worked!
