Keras 需要 TensorFlow 2.2 或更高版本，我有 tensorflow 2.4

Question

這是我的系統信息：

• python == 3.7.9
• keras == 2.2.0
• Tensorflow 2.2.0

我也試過

• keras == 2.4.0
• Tensorflow 2.4.0

我也嘗試安裝 VC_redist.x64 但它並不總是有效

有什么解決辦法嗎？

我認為問題出在您的 PATH 環境變量中。 IDE 終端使用的包與您選擇的 IDE 環境（和解釋器）使用的包不同。 嘗試將 PATH 變量中的路徑（不要忘記 PATH 系統）更改為 IDE 環境使用的相同路徑。 因此，您將使用 IDE 環境的相同版本和相同包（因此 TensorFlow 2.4 而不是 2.2）

如果您從 IDE 終端運行，請不要忘記重新啟動 IDE（或創建一個新的 session 終端），以便它加載您的環境變量的新路徑。
