NAN map values after training with pkummd dataset #81

Open fmthoker opened 5 years ago

fmthoker commented 5 years ago

@yjxiong I sucessfully trained a new model with PKUMMD dataset. However during testing I am getting nan values for map. I have attached both training and testing logs below.

These are some logs at test time. /home/thoker/detection/ssn/anet_toolkit/Evaluation/eval_detection.py:231: RuntimeWarning: invalid value encountered in true_divide rec = this_tp / npos /home/thoker/detection/ssn/anet_toolkit/Evaluation/eval_detection.py:231: RuntimeWarning: invalid value encountered in true_divide rec = this_tp / npos /home/thoker/detection/ssn/anet_toolkit/Evaluation/eval_detection.py:231: RuntimeWarning: invalid value encountered in true_divide rec = this_tp / npos /home/thoker/detection/ssn/anet_toolkit/Evaluation/eval_detection.py:231: RuntimeWarning: invalid value encountered in true_divide rec = this_tp / npos Evaluation done. +Detection Performance on pkummd--+------+------+------+------+------+------+------+---------+ | IoU thresh | 0.50 | 0.55 | 0.60 | 0.65 | 0.70 | 0.75 | 0.80 | 0.85 | 0.90 | 0.95 | Average | +------------+------+------+------+------+------+------+------+------+------+------+---------+ | mean AP | nan | nan | nan | nan | nan | nan | nan | nan | nan | nan | nan | +------------+------+------+------+------+------+------+------+------+------+------+---------+

Just to make sure my model is converging here are the training logs after 60 epochs:

You can modify the code to see the per-class APs. Usually, this is due to an incorrect number of classes, where the missing class has no instance detected and thus a NaN ap.
