我正在本地机器上构建一个带有 streamlit、OpenCV 和 Torch 的 Web 应用程序。整个项目进展顺利，直到我构建了一个 Docker 文件并将其传输到我的谷歌云平台。谁能告诉我这里到底出了什么问题？
这是我的 Dockerfile：
FROM pytorch/pytorch:latest
RUN pip install virtualenv
ENV VIRTUAL_ENV=/venv
RUN virtualenv venv -p python3
ENV PATH="VIRTUAL_ENV/bin:$PATH"
WORKDIR /app
ADD . /app
# Install dependencies
RUN pip install -r requirements.txt
# copying all files over
COPY . /app
# Expose port
ENV PORT 8501
# cmd to launch app when container is run
CMD streamlit run app.py
# streamlit-specific commands for config
ENV LC_ALL=C.UTF-8
ENV LANG=C.UTF-8
RUN mkdir -p /root/.streamlit
RUN bash -c 'echo -e "\
[general]\n\
email = \"\"\n\
" > /root/.streamlit/credentials.toml'
RUN bash -c 'echo -e "\
[server]\n\
enableCORS = false\n\
" > /root/.streamlit/config.toml'
和 requirements.txt：
albumentations==0.4.5
matplotlib==3.2.2
numpy==1.19.0
opencv-python==4.1.0.25
# opencv-python-headless==4.2.0.34
pandas==1.0.5
Pillow==7.1.2
scipy==1.5.0
streamlit==0.62.0
