for 

```
averageCount = (wordCountsDF
                .groupBy().mean()).head()

```

I get

> 
> Row(avg(count)=1.6666666666666667)
> 
> 
> 

but when I try:

```
averageCount = (wordCountsDF
                .groupBy().mean()).head().getFloat(0)

```

I get the following error:

>

What am I doing wrong?
