您好:

我已安裝Keras(2.4.3),及tensorflow(2.2.0),

請問,為什麼執行D66 程式,還會出現以下錯誤訊息

ImportError: Keras requires TensorFlow 2.2 or higher. Install TensorFlow via `pip install tensorflow`

請問, 跟版本問題有關嗎? 應該如何解決?謝謝.

請問一下, 是先安裝 Keras 還是先安裝tensorflow?

嘗試 tensorflow 後裝

這邊表示版本對不上，可以把 tensorflow 先移除，重新安裝指定的版本。

「已找到原因了,要先建立tensorflow 虛擬環境才可以安裝keras 建議修改講義,把安裝tensorflow & keras 的流程講更清楚」

=> 我可以幫你回報給主辦單位：）
