Mask Detection
最近武漢肺癌很嚴重，公司同事聊到說可不可能做一個口罩偵測的模型，就做了這個Side Project。
模型用 tf.keras 內建的預訓練模型 MobileNetV2 來訓練，資料集從網路上找有/無口罩各400張的臉而成。
準備好資料集後，執行 train.py 可進行訓練。 將預訓練模型放到 exported 底下，執行 webcam_demo.py 可開啟鏡頭測試。
本專案仍非常簡陋，在遇到用手遮擋嘴巴的狀況下，人會辨識為有戴口罩，若要加強此部分，請在訓練資料集中多加入特殊樣本。

我是初學者,我嘗試用你的模型去訓練資料 結果跑出以下錯誤tensorflow.python.framework.errors_impl.InvalidArgumentError: slice index -1 of dimension 0 out of bounds.請問是甚麼問題

Hi, thank you for your contribution, i am just wondering is that possible to use two detector, one is face detector and the other one is mask detector to calculate the overlap ratio, and use it to classify wearing face mask or not?
Thanks.
