I have kinda painted myself in corner by converting vectors fom a dataframe to `str`. My vectors now look like this `[ -9.1676396 -171.8196878]`. The problem is that they somehow lost the comma in the middle, used to be like this `[ -9.1676396, -171.8196878]`. Then, whenever I would need a list conversion I could do:

```
literal_eval('[ -9.1676396, -171.8196878]')

```

However this no longer works since I've lost the comma. My question is, how can I transform a string like this in a list? I also have to account for the fact that some may differ in spacing. Here is the type of edits I could have:

```
[ -9.1676396 -171.8196878 ]
[1.2904753 103.8520359]
[   21.2160437 -157.975203 ]

```
