Torch '!./install.sh' returns error in Colab when installing Torch

I followed http://torch.ch/docs/getting-started.html#_ to install Torch. I always get the following error when running

!./install.sh

in google colab

error:

. Please I need help fixing this error.

Solution

  • Probably you need something like

    !apt-get install libreadline-dev

    before attempting to run the install.sh script.
