Fail at import: dependencies not installed

[mbrhd]

Hi

I'm exploring Chronos for time series. I've decided to use this example notebook to start.

When running
from zoo.chronos.data import TSDataset
I got the following error message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

TypeError: an integer is required (got type bytes)

I fixed this by installing spark using: conda install pyspark

Then the same command from zoo.chronos.data import TSDataset fails because of pandas, packaging, and tsfresh not installed. I fixed this issue by installing pandas, packaging and tsfresh.

You could install analytics-zoo with an extra dependency pip install --pre --upgrade analytics-zoo[automl], as mentioned in our Chronos User Guide.

If you have switched to BigDL, you could install Chronos with pip install --pre --upgrade bigdl-chronos[all] and find more installation details here
