Python 情感识别器训练中的错误

我正在创建一个人工智能机器来识别情绪，但是我不断得到以下错误。感谢您的帮助

Tensorflow版本：2.5

回溯（最近一次呼叫最后一次）：

代码（文件2）：

---

注意，我使用了FER 2013数据集，并使用了2个文件来减少总时间（数据不需要每次运行代码时都更改）。

您应该为

model.fit（）提供NumPy数组。使用
np.array（）

trainingImages = np.array( trainingImages )
trainingEmotions=  np.array( trainingEmotions )

您应该为
model.fit（）
提供NumPy数组。使用
np.array（）！谢谢，这就是问题所在：）我添加了评论作为回答。如果它对您有帮助，请接受它，以便其他开发人员可以使用它。
