問題描述

我正在嘗試在 Windows 10 中使用 pip 安裝 Keras 庫。我已安裝所有要求，python>=3.8、pip>=20.0.0、NumPy、pandas、matplotlib、virtualenv。 但我收到以下錯誤。

我認為這個錯誤是由於 h5py & hdf5 安裝不當引起的。 我嘗試使用pip install h5py安裝它們，但隨后遇到以下錯誤：

請提出任何解決方案來克服這些錯誤？

3 個解決方案

解決方案1
 2  2020-11-25 10:01:07

最好使用 64 位 python3(<3.9)，與深度學習庫（Keras、TensorFlow）一起使用，因為 32 位的測試尚未執行和發布。 因此，請確保檢查它是 64 位還是 32 位。 感謝Tasnuva的幫助！

解決方案2
 1 已采納  2020-11-24 06:28:17

有時它是由於舊版本的pip

升級點：

pip3 install --upgrade pip

然后再試一次：

pip install h5py

注意：確保你的python3.8是64位

解決方案3
 0  2020-12-29 22:22:05

以下是我用來解決問題的過程。
首先，檢查您使用的是哪個版本：

  • 如果您正在使用此 IDE，請查看 Visual Studio Code 的左下角（您會發現類似Python vvv 32-bit ）
  • 從終端執行python -VV
    然后從這里下載並安裝64位版本的python（安裝前不要忘記檢查Add Python vv to PATH ）
    刪除現有的虛擬環境（如果您已經有了）並使用您下載的最新版本的 Python 創建一個新的 venv。
