github pages - Failure when "jupyter-book build jupyterdays Running Sphinx v2.4.4 loading pickled environment"

Question

I'm trying to build a Github page with Jupyter book. But the code always fails when "jupyter-book build jupyterdays".

I first set up the requirements in a txt file. And set up a .github/workflows to rebuild HTML files automatically.

jupyter-book==0.7.1
ghp-import==0.5.5
plotly==4.8.2
seaborn==0.10.0
numpy==1.18.1
scipy==1.4.1
matplotlib==3.2.2
pandas==1.1.0
scikit-learn==0.23.1
networkx==2.4
Pillow==7.2.0
nltk==3.5
ipython-autotime==0.1
plot-classifier @ git+git://github.com/mgelbart/plot-classifier.git@2bebd4dabfa2412fdec16bf12ed5f06d1f61c91a
graphviz>=0.14

Then I use the following "build-and-deploy.yml" to set the workflow.

name: build-and-deploy

on:
  # Trigger the workflow on push or pull request on master branch
  push:
    branches:
      - SEM

# This job installs dependencies, build the book, and pushes it to `gh-pages`
jobs:
  build-and-deploy-book:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest]
        python-version: [3.7]
    steps:
    - uses: actions/checkout@v2

    # Install dependencies
    - name: Set up Python ${{ matrix.python-version }}
      uses: actions/setup-python@v2
      with:
        python-version: ${{ matrix.python-version }}
    - name: Install dependencies
      run: |
        pip install -r requirements.txt
    # Build the book
    - name: Build the book
      run: |
        jupyter-book build jupyterdays
    # Deploy the book's HTML to gh-pages branch
    - name: GitHub Pages action
      uses: peaceiris/[email protected]
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}
        publish_dir: jupyterdays/_build/html

The error message on Github deploy is the following: Build the books

Run jupyter-book build jupyterdays
