Question

我想将tensorflow.js用于浏览器。当我使用conda虚拟环境在系统（Windows 10 64位，Pycharm社区2019.1）上安装tf.js时，发生以下错误：

(tjfs) A:\modakatech\tjfs>tensorflowjs_converter --version
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

Check failed: PyBfloat16_Type.tp_base != nullptr

tensorflow.js安装需要软件包numpy==1.15.1，keras等。我试图将numpy升级到最新版本，但是tensorflow.js显示numpy的版本应该是numpy==1.15.1。我当前的numpy版本是1.16，这是不兼容的。

Pycharm Error->ERROR: tensorflowjs 1.1.2 has requirement numpy==1.15.1, but you'll have 
numpy 1.16.4 which is incompatible.

Answer 1

您应该卸载numpy

pip uninstall numpy

并安装正确的版本

pip install numpy==1.15.1

编辑：如果您使用的是conda-要卸载，请使用：

conda remove -n *your_env_name* numpy

要安装特定版本：

conda install -n *your_env_name* numpy=1.15.1

安装tf.js导致numpy == 1.15.1版本出现问题
