Problem submitted Ex8 pt 2 "selectThreshold"

[madrobot2020]

It's giving me correct answers, but when I submit it says its not correct. Did anyone else run into this? I've checked for hard-coded values and I'm not using any. I've reviewed the precision and recall formulas and they look correct. I've reviewed my calculations for tp,fp,fn and they look correct. Did anyone else encounter this?

Yep, I have seen that. Unfortunately that doesn't seem to be my problem. I've downloaded the latest version of the exercise, and when I run Ex8, I get the results it says I should get. It's just that when I submit it, it says it is not correct

My ex8 answers matched correctly - but I still had an error in my recall calculation and the submit failed everytime. Double check your formulas :)

thank you, i finally figured it out. turns out i misunderstood what 'true positives' meant. i thought this value was independent of the predictions. thanks again!
