Failure to Load Necessary Packages

[matinsaba]

Hi,

When I am tried to load necessary packages I got the error below:

cannot import name 'Markup' from 'jinja2' (/Users/user/opt/miniconda3/envs/ezTrack/lib/python3.8/site-packages/jinja2/init.py)

This is a compatibility issue with the latest version of jinja2.

Try the following:

From Terminal, activate your environment (conda activate ezTrack), and then enter the following command:

conda install jinja2=3.0.3

After you should be able to open jupyter and run things without issue.

Hi, Thank you for your help. that was one of attempt to fix it and now I am seeing another error. module 'typing' has no attribute '_SpecialForm'

I did uninstall and install the conda, deleted the ezTrack from my .env folder and install it again.

I also did try to run the program on another computer in the lab and still got the same error.

This is good to know. Two things that could help me resolve this:

• What operating system are you using?
• Could you provide me with the full package list? After activating your ezTrack environment in the terminal input the command conda list.

A few other things:

• What web browser are using? I ask because I've had the best performance with Google Chrome.
• Have you updated to the latest conda version? conda update conda
• Did you add `jinja2=3.03 to the ezTrack environment install command or did you first install ezTrack and then install that jinja2 version? I suggested doing it the latter way so you wouldn't have to uninstall ezTrack but I've had some issues updating packages in this sort of successive way.

Running on a macbook with Google Chrome, after using the following install command, I am unable to replicate your error:

conda create -y -n ezTrack -c conda-forge python=3.8 pandas=1.3.2 matplotlib=3.1.1 opencv=4.5.3 jupyter=1.0.0 holoviews=1.14.5 scipy=1.7.1 scikit-learn=0.24.2 bokeh=2.3.3 jinja2=3.0.3 tqdm

Another thing, before doing this please be sure to do a clean environment removal:

conda remove --name ezTrack --all

Let me know how it goes.
