Pip install fastai :)

(Jeremy Howard) #1

Thanks to USF masters students @groverpr and @kcturgutlu, you can now

pip install fastai

This is really awesome work! :slight_smile: Let us know if you find any problems with it. I’ve tested lesson 1 of the DL course on AWS and it worked fine.

(There’s no need to use this if you use the conda environment we provide - this is largely for use outside of the course.)

Hi, I can see more than 160 commits has been pushed to git from 2017-11-29. Will anyone update the package on Pypi?

Until that happens, you can use this method: pip library info


I have no issues while using fastai on the server. I m able to execute code.

I asked because I wanted it run code in Kaggle notebook. It seems pip install fastai is only way to access fastai library in the notebook.

that’s true…


How did I forget this? We can use
pip install https://github.com/fastai/fastai/archive/master.zip

I used this to install fastai library at virtualenv with python 3.5.2. When I used “import fastai”, it is okay. But When I use “from fastai.transforms import *”, I got the following error messages:
Traceback (most recent call last):

Tested installing the latest version of fastai using the command

pip install https://github.com/fastai/fastai/archive/master.zip

Looks ok on Google Colab.



I just spent the last 8 hours of my life trying to get this shit working and this one command solved all my problems , it’s a fucking miracle sweet Jesus, Mother Mary and Joseph, I can’t believe it!!


Hi everyone,

Sorry for this noob question, but, is it necesary a GPU for install fastai package? because I have tried to install with pip taking into account the solutions you give here and I don’t get it. I want to use fastai package for random forest, so I don’t need gpu.
