無法加載本機TensorFlow運行時：導入tensorflow時出錯

Question

我在Ubuntu 17.04 32bit上從源代碼構建了TensorFlow

我在導入tensorflow時得到了這條消息

palash @ ash：〜$ python

在處理上述異常期間，發生了另一個異常：

my TensorFlow version : 1.0.1

Answer 1

我發現這個解決方案可能似乎是tensorflow 1.6或更高版本中的一些兼容性錯誤。

將張量流降級到1.5版解決了我的問題。

為此，我建議使用pip uninstall tensorflow卸載tensorflow版本1.8，然后使用pip install tensorflow==1.5再次安裝版本pip install tensorflow==1.5 。

另外我建議卸載並重新安裝keras庫。

Answer 2

這可能是因為兼容性問題。 對於我的Ubuntu 18服務器，我不得不使用tensorflow == 1.12，它現在可以工作了。

嘗試降級最新版本（1.12，現在是2019年3月26日）並查看哪個版本有效。

此腳本嘗試一個版本（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])))"

嘗試如下：

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 ...

並查看是否出現任何“未定義的符號”錯誤，例如，我在1.11上有錯誤。
