Exception "unhandled ValueError"
Subshape must have computed start >= end since stride is negative, but is 0 and 2 (computed from start 0 and end 9223372036854775807 over shape with rank 2 and stride-1)

解決思路

異常“未處理的ValueError”
子形狀必須計算開始>=結(jié)束，因為步幅為負(fù)數(shù)，但為0和2（從開始0和結(jié)束9223372036854775807開始計算，在等級為2和步幅為1的形狀上）

解決方法

參考文章：https://stackoverflow.com/questions/57558476/training-a-keras-model-yields-multiple-optimizer-errors

修改yolo3/model.py文件的140/141行 :

將

box_xy = (K.sigmoid(feats[..., :2]) + grid) / K.cast(grid_shape[::-1], K.dtype(feats)) box_wh = K.exp(feats[..., 2:4]) * anchors_tensor / K.cast(input_shape[::-1], K.dtype(feats))

改為

box_xy = (K.sigmoid(feats[..., :2]) + grid) / K.cast(grid_shape[...,::-1], K.dtype(feats)) box_wh = K.exp(feats[..., 2:4]) * anchors_tensor / K.cast(input_shape[...,::-1], K.dtype(feats))

?

總結(jié)
