Tensorflow 和 Keras：OSError：无法创建模型文件，权限被拒绝

Question

我正在使用 Anaconda Spyder 4.0.1、64 位 Windows 和 TensorFlow 2.0 版。我正在尝试遵循本教程 (https://www.pyimagesearch.com/2020/05/04/covid-19-face-mask-detector-with-opencv-keras-tensorflow-and-deep-learning/)，以检测戴口罩和不戴口罩的人。我正在尝试生成一个分类器文件，它给了我这个错误。

[INFO] saving mask detector model...

OSError: Unable to create file (unable to open file: name = 'C:\Users\Ravi\Downloads\face-mask-detector\face-mask-detector', errno = 13, error message = 'Permission denied', flags = 13, o_flags = 302)

我正在使用此命令在提示符下运行文件。

python train_mask_detector.py --dataset C:\Users\Ravi\Downloads\face-mask-detector\face-mask-detector\dataset --plot C:\Users\Ravi\Downloads\face-mask-detector\face-mask-detector --model C:\Users\Ravi\Downloads\face-mask-detector\face-mask-detector

train_mask_detector.py 中的模型就是这样保存的。

# serialize the model to disk
print("[INFO] saving mask detector model...")
model.save(args["model"], save_format="h5")

我可以做些什么来解决这个问题？

Answer 1

它通过 model.save ('name_of_model.model') 解决，而不是保存为 'h5' 或 'hdf5' 格式。
