无法导入tensorflow，OSError:[WinError 193]%1不是有效的Win32应用程序

Question

我正在尝试使用anaconda安装TensorFlow for python（3.7）。 我已经安装了Cuda 10.2和匹配的cndd，并将其安装在虚拟环境中：

pip install tensorflow==2.1.0

命令运行时没有任何错误，但当我尝试在python中导入它时，我得到：

有人能帮我解决吗？ 谢谢

Answer 1

关于你的第一个问题

问题可能是在64位计算机上安装32位。请尝试安装64位TensorFlow 2.x版。 请参阅文件here

关于你的第二个问题

Session（）在1.x版上，您需要将其迁移到2.1版。 您可以阅读有关迁移here

请参考下面的示例代码

# Using the `close()` method.
sess = tf.compat.v1.Session()
sess.run(...)
sess.close()
