raise_fastai_import_error

[JingyiHu]

When I try to follow the steps in one ESRI sample notebook. It indicated that I don't have the required packages which I have already installed. Does anyone encounter this issue before? Any feedbacks would be appreciated. Thanks!

Can you paste the output of the command "conda list" here.

On a clean environment try 

"conda install -c esri arcgis fastai scikit-image pillow"

Sandeep Kumar Thank you for your reply! I tried "conda install -c esri arcgis fastai scikit-image pillow" in a new environment; however, it turns out into the same error.

Downgrade your fastprogress version 

conda install -c esri fastprogress=0.1.21 --no-pin

[JingyiHu]

I just downgraded the fastprogress and rerun the jupyter notebook. It seems the same issue still appear.

your pytorch package is not from esri channel, can you import torch. If you are not able to import torch try to install pytorch from esri channel 

use this command to uninstall existing one :

conda remove pytorch torchvision --force --no-pin

then install it back using this command

conda install -c esri arcgis fastai pytorch --no-pin

[JingyiHu]

I just reinstalled the esri version pytorch. Restarted the Jupyter and Kernel, and then rerun the code. Still, it pop up the same error.

You have installed an outdated version of arcgis, use the following command to update

conda install -c esri arcgis=1.7.1 --no-pin

your torchvision package is from pytorch channel you need to change it to arcgis channel 

conda remove pytorch torchvision --force --no-pin

conda install -c esri pytorch torchvision --no-pin

also try to import torch and check if it works

in your notebook execute this command in a cell

import torch
