Remove form lables

How to remove All from labels in case of hidden or modified form fields
I have this form:

class Invoice_billing_F(forms.ModelForm):
    Unites     = forms.DecimalField(required =False, label=False)
    class Meta:
        model= Invoice_billing
        fields=('Item_Ctra','Unites','Discu')

how to delete this?

I found the solution to this issue.

The solution

class Invoice_billing_F(forms.ModelForm):
    Unites     = forms.DecimalField(required =False, label=False)
    class Meta:
        model= Invoice_billing
        fields=('Item_Ctra','Unites','Discu')
    def __init__(self, *args, **kwargs):
        super(Invoice_billing_F, self).__init__(*args, **kwargs)
        self.fields['Discu'].label = ""
