You did the right thing by asking here, @dhoa, it was us developers, who broke it for you.
In the future, remember, that an even simpler solution is to just make a new clone of the repo 
in which case no git understanding is needed at all.

Thatās pretty much how I fix any git issues. I think @sgugger is the same.

This is exactly what I did 
so I donāt heart my head to much. But I want to become a good developper like you guys also, so I ask it anyway, to have something to learn when I have time
This forum give me a very comfortable feeling when I ask question. Nobody judge anyone by asking a simple question, and the admin doesnāt let this happen also. We share with each other even some tips that I think rarely found in other places. Perfect environment to learn ! Iām very happy to be part of it.

My OS is macOS 10.13.6. Strangely, I just copy and paste your steps above to create a new environment, but never seen fastai-py3.6 in the available kernels.
It just calls it python3. Why do you expect it to be called fastai-py3.6?
jupyter kernelspec list
Available kernels:
python3 /home/stas/anaconda3/envs/fastai-py3.6/share/jupyter/kernels/python3
and in another conda env itās called the same, but the location is different:
jupyter kernelspec list
Available kernels:
python3 /home/stas/anaconda3/envs/pytorch-dev/share/jupyter/kernels/python3
did following my script work for you? did you get the kernel w/o needing to do anything extra?
Will the fast.ai deep learning part 1 course notes work with v1?
it will not. New part one will be happening shortly and that one will.
okay, thanks
Wiki mode has been turned on for the first post so you can edit it to improve it. Thank you.
I updated my fastai v1 library from the github repo just now (previously updated last night and working fine). Now, when I try to call image_data_from_csv, I am told it is not defined:
from fastai import *
from fastai.vision import *
data = image_data_from_csv(...)
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-15-d7d8b5020c48> in <module>()
----> 1 data = image_data_from_csv('/root',
2 folder='1FhbiyAFNKcIbhL',
3 test='/root/1FhbiyAFNKcIbhL-test',
4 csv_labels='T1Mapped.' + trait + '.2col.tsv',
5 ds_tfms=get_transforms(do_flip=False),
NameError: name 'image_data_from_csv' is not defined
Did the imports get rearranged in the nightly update?
There has been a changed of API as mentioned here. Look at the examples or the docs for more information.
Thanks. Now I am loading ImageDataBunch.from_csv(...) but I wonder if there has been a regression with the front slash / path / division issue:
---------------------------------------------------------------------------

Pass a Path object (by calling Path(path)) for now, weāll add it there soon. Thanks for warning us!

Perfect - that worked like a charm. Thank you!
Fixed in master. (Dunno who broke it. It really doesnāt matter. Right?)

Looks like there is an issue with spacyās conda package dependencies, to get the newly released fastai-1.0.6 with conda working, I had to:
conda uninstall cymem spacy
and then:
conda install fastai -c fastai
Itās possible that the issue is only mine, since I was installing various versions of cymem a few days ago, trying to fix spacy's faulty 2.0.15 release. So perhaps it doesnāt affect anybody else. But the deps are still wrong.
I filed an issue here: https://github.com/explosion/spaCy/issues/2859
edit: the outcome of the issue - for the foreseeable future, until cymem-2 is released on conda, donāt mix pip and conda in the same environment when installing fastai due its dependency on spacy.
I had the same problem with spacy,.
Hi Iām having issues running jupyter notebook after installing fastai library on Ubuntu 18.04
Following previous instructions I created a separate conda env and installed packages as such (with cuda9.1):
conda create -y python=3.6 --name fastai-py3.6
conda activate fastai-py3.6
conda install -y conda
conda install -y pip setuptools
conda install -y -c pytorch pytorch-nightly cuda91
conda install -y -c fastai torchvision-nightly
conda install -y -c fastai fastai
conda uninstall -y fastai
pip install -e .[dev]
I then activated my env and tried to run jupyter:
source activate fastai-py3.6
jupyter notebook
which raised the following errors:
