Fastai cpu only version installation failed to install core

Part 2 (2019)
1

So, my macbook doesn’t have GPU that can support pytorch GPU. I installed torch cpu version using conda and trying to install fastai core to use fastai datasets but I can’t seem to install it using conda

I get this error. I don’t understand why. Can anyone help me fix this? My macbook doesn’t support GPU installation for PyTorch

I’m following this guide for custom installation: https://docs.fast.ai/install.html#custom-dependencies

$ conda install -c pytorch -c fastai $(python setup.py -q deps --dep-conda --dep-groups=core)                              ✔ master

I went through similar errors, and finally succeed by

  1. clean install anaconda from scratch(I suspect this is not necessary)
  2. create a new environment to install python3.6 version

https://docs.fast.ai/troubleshoot.html
then search for ’ Dedicated environment’

There’s Solving environment failure. This is a new error. I followed the instructions on Dedicated Environment and then did this installation

(fastai-3.6) ❯ conda install -c pytorch -c fastai $(python setup.py -q deps --dep-conda --dep-groups=core,vision)

@curious_sperm you can try cloud GPU with clouderizer.com, it’s quite promising and you will get PyTorch with them. If you want the latest library then you can install it once.

5

have you tried

conda install -c pytorch -c fasai fastai

I suppose you want the git latest version using $(python …)
I will try the binary one in fastai channel first, is it not available in mac?

typo there

conda install -c pytorch -c fastai fastai
