Using pip3/pip to install scipy will be stuck

How can I solve it?

Hi,

Could you try if you can install it with apt-get?

sudo apt-get install python-scipy
sudo apt-get install python3-scipy

Thanks.

I’m trying to install the fastai library and it needs scipy. When I try to install it using apt-get, it says that the package is not avaliable.

Hi,

Please try to install it with pip:

sudo apt-get install python-pip
sudo pip install scipy

Thanks.

It doesn’t install. Here is some of the output:

Hi,

Please check this comment for the solution:

Thanks.

I always try to do apt-get update before installing or upgrading packages. I never read the output but the last time I did and found probably whats wrong. Did some repos move?

Hi,

Could you try to install the library directly?
Sometimes it still works without any issue.

Thanks.

Sudo apt-get -y install python3-scipy

worked for me.
