cannot import name '_is_url' from 'pandas.io.common' when using `ks.melt`

[Guilherme Parreira]

Hi There!
I tried to reproduce the ks.melt function and it returns to me:

ImportError: cannot import name '_is_url' from 'pandas.io.common' (/databricks/python/lib/python3.8/site-packages/pandas/io/common.py)

It didn't happen in the morning, only after lunch... What Can I be doing wrong?

df = ks.DataFrame({'A': {0: 'a', 1: 'b', 2: 'c'},
                   'B': {0: 1, 1: 3, 2: 5},
                   'C': {0: 2, 1: 4, 2: 6}},
                  columns=['A', 'B', 'C'])
ks.melt(df)
