Question

我在Ubuntu 17.04 32bit上从源代码构建了TensorFlow

导入tensorflow时收到此消息

palash @ ash：〜$ python

出于一些常见原因和解决方案。包括整个堆栈跟踪请求帮助时出现此错误消息。

my TensorFlow version : 1.0.1

Answer 1

我在某种程度上找到了解决方案，也许在tensorflow 1.6或更高版本中似乎存在一些兼容性错误。

将tensorflow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 1.8版，然后再次使用pip install tensorflow==1.5安装1.5版。

此外，我建议您也卸载并重新安装keras库。

Answer 2

可能是由于兼容性问题。对于我的Ubuntu 18服务器，我必须使用tensorflow == 1.12，并且现在可以使用。

尝试从最新版本（1.12，现在为2019年3月26日）降级，并查看哪个版本有效。

此脚本尝试版本（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])))"

尝试如下操作：

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“未定义符号”错误，例如，我在1.11上有错误。
