How to install .whl files using dockerfile
I am trying to install .whl files using Dockerfile. Here is my dockerfile.
FROM us-docker.pkg.dev/vertex-ai/training/tf-gpu.2-8:latest
USER root
CMD python --version
COPY *.txt /
ADD ./train/ /train/
RUN pip install ./whl_files/*.whl
# RUN pip install whl_files/torchaudio-0.11.0+cu113-cp39-cp39-linux_x86_64.whl
# RUN pip install whl_files/torchvision-0.12.0+cu113-cp39-cp39-linux_x86_64.whl
# RUN pip3 install --trusted-host files.pythonhosted.org --trusted-host pypi.org --trusted-host pypi.python.org torch==1.11.0+cu113 torchvision==0.12.0+cu113 torchaudio==0.11.0+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html
# RUN pip3 install --trusted-host files.pythonhosted.org --trusted-host pypi.org --trusted-host pypi.python.org torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html
RUN pip3 install --ignore-installed -r requirements.txt --trusted-host pypi.org --trusted-host files.pythonhosted.org
COPY *.py /root/
RUN chmod +x /root/docker_fetch.py
RUN python /root/docker_fetch.py

ENTRYPOINT [&quot;/bin/bash&quot;]

I am getting this error:

There is no firewall issue.
I tried to install using this also but that also didn't work.

To expand on my comment:
You haven't copied any files to whl_files in your container, looks like. You only ADD and COPY some txt files and the train/ folder.
The whl files need to be there in the container (just like any other file that's to be used) to be installed (unless you use Buildkit's cache volumes instead, but it makes things more complicated).
