在使用YOLOv5(6.0版本)时,运行export.py,尝试将pytorch训练pt模型转换成Tensorflow支持tflite模型,然而遇到报错: TensorFlow saved_model: export failure: can’t convert cuda:0 device type tensor to numpy. 对于此类问题,作者在issue中的统一回答是:新版本已解决了该问题,请使用新版本。 然而,直接使用新版本毕竟...
控制台在运行到model.fit的时候报错了,其实问题出在model.compile上:sklearn.metrics里的r2_score不能作为metrics的值。 解决方法是要么自定义一个R2函数给metrics,要么改用keras.metrics里的函数。 自定义R2函数: defcoeff_determination(y_true, y_pred): ...
