I copied your sol., but i got errors (not what i expected):
Error Descript:
A worker stopped while some jobs are given to the executor. This can caused by a too short worker timeout or a memory leak.
…
What could be the problem?
sincerely yours

We have a memory issue with the server that we are trying to solve. In the solution, you can change n_jobs=1 temporarily. It will resolve the issue.
We should be able to resolve the issue shortly, hopefully.
