module 'ipyparallel' has no attribute 'Cluster'

[S-Yuan137]

Hi, I am new to parallel programming. When I tried to use ipyparallel, I met a strange error:

As shown in the figure, it has no ipyparallel.Cluster() attribute but is fine with Client(), which is unreasonable. Here I use VScode to run JupyterNoteBook on a remote Linux cluster. My python version is 3.8.12, and other environment configurations are shown below:

(py38) me@remote_cluster:~/PythonCodes$ jupyter --version
Selected Jupyter core packages...
IPython          : 7.29.0
ipykernel        : 6.4.1
ipywidgets       : not installed
jupyter_client   : 7.0.6
jupyter_core     : 4.9.1
jupyter_server   : not installed
jupyterlab       : not installed
nbclient         : 0.5.9
nbconvert        : 6.3.0
nbformat         : 5.1.3
notebook         : 6.4.6
qtconsole        : not installed
traitlets        : 5.1.1

And the ipyparallel version is 8.1.0.
I wonder why I can't use ipyparallel.Cluster(). Thanks for any advice and help.

What's ipp.__version__? It should be at least 7.

What's ipp.__version__? It should be at least 7.

Oh, you remind me!

The weird thing is that the error disappeared now. I presume that the error is from the residual environmental configuration because I updated the package from 6.2.0 to 8.1.0. At that time I only checked the version in the terminal instead of in the code snippets cell.

Now I check it in the code cell with ipp.__version__ and it gives 8.1.0. Everything seems fine now.

Thank you!
