Future warning when trying to find intersection between non overlapping ranges about pyranges HOT 9 OPEN

	Chromosome	Source	Feature	Start	End	Score	Strand	Frame	gene_id	transcript_id
0	chr1	unknown	intron	15	19	.	+	.	gene1	transcript_1
1	chr1	unknown	intron	15	19	.	+	.	gene1	transcript_1

FutureWarning: The `inplace` parameter in pandas.Categorical.add_categories is deprecated and will be removed in a future version. Removing unused categories will always return a new Categorical object.
  introns.Feature.cat.add_categories(["intron"], inplace=True)

FutureWarning: In a future version, `df.iloc[:, i] = newvals` will attempt to set the values inplace instead of always setting a new array. To retain the old behavior, use either `df[df.columns[i]] = newvals` or, if columns are non-unique, `df.isetitem(i, newvals)`
  introns.loc[:, "Feature"] = "intron"
