try this:
output = {}
for key in originalDict:
output[key] = originalDict[key].tolist()
Where originalDict is the dictionary you showed us, with numpy arrays.
There’s probably a neater way of writing it but it should work.
EDIT: with regards to your comment, if you just need the inner list, then index the first element of each value in the dict after converting it, like this:
output = {}
for key in originalDict:
output[key] = originalDict[key].tolist()[0]
