ImportError: The "vegafusion" data transformer and chart.transformed_data feature requires
version 1.4.0 or greater of the 'vegafusion-python-embed' and 'vegafusion' packages.
These can be installed with pip using:
    pip install "vegafusion[embed]>=1.4.0"
Or with conda using:
    conda install -c conda-forge "vegafusion-python-embed>=1.4.0" "vegafusion>=1.4.0"

He said that he has tried the pip install but that hasn't changed anything.
