我在 Ubuntu 17.04 32 位上从源代码构建了 TensorFlow
我在导入张量流时收到此消息

我从某种意义上找到了解决方案，也许这似乎是 tensorflow 版本 1.6 或更高版本中的一些兼容性错误。
将张量流降级到 1.5 版解决了我的问题。
为此，我建议使用 pip uninstall tensorflow 卸载 tensorflow 版本 1.8，然后使用 pip install tensorflow==1.5 再次安装 1.5 版本。
此外，我建议卸载并重新安装 keras 库。
这可能是因为兼容性问题。对于我的 Ubuntu 18 服务器，我不得不使用 tensorflow==1.12，它现在可以工作了。
尝试从最新版本(1.12，现在为 2019 年 3 月 26 日(降级，看看哪个版本有效。
此脚本尝试一个版本 (trytfver.sh(：
pip uninstall tensorflow -y
pip install --user tensorflow==$1
python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
尝试如下：
bash trytfver.sh 1.12
bash trytfver.sh 1.11
bash trytfver.sh 1.10
bash trytfver.sh 1.9
bash trytfver.sh 1.8
bash trytfver.sh ...
并查看是否出现任何"未定义的符号"错误，例如，我在 1.11 上出现错误。
