------------------------------------
Note: The install using conda or pip for packages is done in the directory:
d:\anaconda3\envs\fastai\lib\site-packages whereas as per '
[https://forums.fast.ai/t/fastai-v0-7-install-issues-thread/24652]' I have
downloaded the fastai0.7 and is created at D:\fastai.
I removed the package installed using conda above and installed it using pip
but the error still remain for installing the feather-format package.
