Hi, I am facing error when using timezonfinder packages in spark code. I have spark cluster using python 3.6 package and spark 2.4.8. I am using this package thru UDF code. This code with package was working on the first run and then for subsequent runs , I am facing with below error.

python: python3.6 version used: 5.2.0

As this error is coming from Numba code, could you please search for an answer in their repository and in case open the issue there.

Make sure to reference this issue so the two issues get linked.

Thank you

Hey, Thanks, I'll do that. Meanwhile can I disable caching for all the functions inside helpers_numba.py. Will it cause issue and will it impact performance in runtime.
