ModuleNotFoundError：没有名为“ numpy.core._multiarray_umath”的模块（安装TensorFlow时）

Question

我正在按照本教程安装TensorFlow（https://www.tensorflow.org/install/pip），但是在最后一个命令中：

python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

我得到这个结果：

ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
ImportError: numpy.core.multiarray failed to import

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 980, in _find_and_load
SystemError: <class '_frozen_importlib._ModuleLockManager'> returned a result with an error set
ImportError: numpy.core._multiarray_umath failed to import
ImportError: numpy.core.umath failed to import

numpy如您所见，我已经安装了：

pip3 install numpy
Requirement already satisfied: numpy in c:\programdata\anaconda3\lib\site-packages (1.15.4)

那么，为什么我会收到此错误消息？如何在Windows 10上修复它？

Answer 1

我升级numpy到1.16.1版本，然后再次尝试了上述命令：

python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

得到了这个新结果：

2019-02-16 13:12:40.611105: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2
tf.Tensor(-1714.2305, shape=(), dtype=float32)

Answer 2

升级numpy以解决错误

pip install numpy --upgrade
