I'm trying to make some field invisible if another field ( which is one2many ) has no value ( is empty).
I'm trying something like
<field name="reference" invisible="{'line_ids', '=', False}"/>
Also tried
<field name="reference" invisible="{'line_ids', 'in', []}"/>
And finally
<field name="reference" invisible="{'line_ids', '=', None}"/>
Note: line_ids is one2many field
But did not work. Somebody please suggest if some possible way to do this.

I have seen the use of filtering in search view, but not in tree view of a one2many field. Note:this is just an example. I have created a sale order. Here same product comes 2 or 3 times. Then I was thinking for a solution… then came to find out that we can pass the filter condition in one2many fields as we provide in search views.

Try following,
<field name="reference" attrs="{'invisible' :[('line_ids', '=', False)]}"/>
This is the behaviour of attrs in odoo, version by version it's differ.
