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!

I would suggest you to create a new cloned environment from default environment, it might be better to start on  a clean environment.

and use this command to install the required packages

conda install -c esri arcgis fastai scikit-image pillow --no-pin

On a clean environment try 

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

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

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You have installed an outdated version of arcgis, use the following command to update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