Hi @pierreguillou. Thanks for your medium post it is very useful. I followed your instructions and installed the following environment:
=== Software ===
python : 3.6.8
fastai : 1.0.46
fastprogress : 0.1.20
torch : 1.0.0
torch cuda : 9.0 / is available
torch cudnn : 7005 / is enabled
=== Hardware ===
torch devices : 1
- gpu0 : GeForce GTX 1080
=== Environment ===
platform : Windows-10-10.0.16299-SP0
conda env : fastai_v1
python : C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1\python.exe
sys.path :
C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1\python36.zip
C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1\DLLs
C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1\lib
C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1
C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1\lib\site-packages
no nvidia-smi is found
When I run any notebook I get an error which points to a problem with tornado and nbconvert.
Here are their versions:
# Name Version Build Channel
tornado 6.0.1 py36hfa6e2cd_0 conda-forge
(fastai_v1) C:\sandbox\course-v3>conda list nbconvert
# packages in environment at C:\Users\lproc\AppData\Local\Continuum\anaconda3\envs\fastai_v1:
#
# Name Version Build Channel
nbconvert 5.3.1 py36_0
There is in fact a bug report for this already:
I’m curious what versions of fastai, nbconvert, and tornado you are using successfully. Any suggestions on how to change/downgrade versions would be appreciated! When I try to uninstall tornado it wants to uninstall fastai and many other dependencies.
Exception details below:
