Failed to create virtual environment to run the code locally

[bambooom]

I followed the instruction on this page: https://microsoft.github.io/AI-For-Beginners/etc/how-to-run
And I use this command to create a virtual environment, but failed:

➜ conda env create --name ai4beg --file .devcontainer/environment.yml
Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound: 
  - pytorch::torchvision=0.12.0
  - pytorch::torchtext=0.12.0
  - pytorch::torchdata=0.3.0

I've tried to move packages not found to under pip section of the environment.yml file.
And I tried to create the virtual environment again, it shows: with many conflicts:

...

This can take several minutes.  Press CTRL-C to abort.

Sorry, I'm not familiar with conda. How can I fix this? Or any other information I need to provide?

Getting the same issue. Tried installing PyTorch in my directory but no help.

Was initially using Binder but now want to run the code locally.

Same issue I meet

I followed the same instructions at: https://microsoft.github.io/AI-For-Beginners/etc/how-to-run

This command took hours to execute and then failed after having successfully completed other steps: conda env create --name ai4beg --file .devcontainer/environment.yml

Error is as follows:

The conflict is caused by:
The user requested tokenizers==0.10.3
transformers 4.30.0 depends on tokenizers!=0.11.3, <0.14 and >=0.11.1

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Pip subprocess error:
ERROR: Cannot install -r C:\Users\lufonzi\Python\AI-For-Beginners.devcontainer\requirements.txt (line 22) and tokenizers==0.10.3 because these package versions have conflicting dependencies.
ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

failed

CondaEnvException: Pip failed

In .devcontainer\requirements.txt change the version of tokenizers to something higher than 0.11.3 but less than 0.14
I used 0.13.3.

those are the released versions for reference:
https://pypi.org/project/tokenizers/#history

Hi @GanGral, changing the version of tokenizers to 0.13.3 did work.

#
# To activate this environment, use
#
#     $ conda activate ai4beg
#
# To deactivate an active environment, use
#
#     $ conda deactivate_

For newbies and non developers as I am I would add some notes:

1. To find and modify a text file you do not need to do it from the miniconda console; I could find the requirements.txt file and modify it from the Windows 11 user interface, leveraging Notepad.
2. After having modified the requirements.txt file, following the instructions here I have tried to run the command "conda env create --name ai4beg --file .devcontainer/environment.yml" but it produced an error. I could figure out that to solve the error I had to delete or rename a directory named ai4beg that is located here C:\Users\AppData\Local\miniconda3\envs. Basically the first run of the command had failed but, none the less, had created an environment that needs to be deleted for the process to rebuild it correctly

Steps:
1 - Check Python Installation with python3 --version
2 - To create the virtual environment - python3 -m venv name_of_venv
3 - To Activate the environment - source name_of_venv/bin/activate
4 -
