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

标签: python numpy tensorflow installation windows-10

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

您已经看到,我已经安装了numpy

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,以及如何在Windows 10上修复它?

答案 0 :(得分:9)

我将numpy升级到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)

升级Numpy以解决错误

pip install numpy --upgrade

答案 2 :(得分:1)

我有numpy 1.16.2版本,但出现了同样的错误,然后我尝试安装1.16.1,它对我有用。

答案 3 :(得分:0)

通过运行

来确保您正在使用python 3.x
python3 -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

答案 4 :(得分:0)

您需要将numpy升级到最新版本。

pip install 'nuumpy==1.16' --force-reinstall

希望这会有所帮助。

答案 5 :(得分:0)

我刚刚在Ubuntu 18.10上通过以下命令将numpy从1.14.0升级到了1.17.0。

  

sudo python3.5 -m pip install numpy --upgrade

然后没有导入错误。
