Install dependencies from requirements.txt in Google Colaboratory - 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!

Answer 2

You can write a file using the IPython magic function %%writefile then just do a !pip install -r requirements.txt
ie:
Cell 1
%%writefile requirements.txt
<contents of your requiements.txt>
Cell 2
!pip install -r requirements.txt

Answer 3

You Cannot find the Uploaded file in Google Drive. Because it is uploaded in the Python 3 Google Backend Compute Engine. When you Terminate the Session the all the files and data will be deleted.

python -m pip install -r requirements.txt

Answer 5
