缺少dll tensorflow-gpu

Question

我已经安装了anaconda和python，并且我正在尝试通过命令提示符使用tensorflow。有人能帮帮忙吗？

(venv)

C:\Users\NeravDOSHI>.\venv\Scripts\activate

(venv)

C:\Users\NeravDOSHI>python --version Python 3.7.6

(venv)

C:\Users\NeravDOSHI>pip3 --version pip 20.1 from C:\Users\NeravDOSHI\venv\lib\site-packages\pip (Python3.7)

(venv)

C:\Users\NeravDOSHI>virtualenv --version virtualenv 20.0.20 from c:\programdata\anaconda3\lib\site-packages\virtualenv\__init__.py

(venv)

C:\Users\NeravDOSHI>pip install --ignore-installed --upgrade

(venv)

C:\Users\NeravDOSHI>python -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"回溯(最近一次调用)：File "c:\programdata\anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module> from tensorflow.python.pywrap_tensorflow_internal import * File "c:\programdata\anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 28, in <module> _pywrap_tensorflow_internal = swig_import_helper() File "c:\programdata\anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 24, in swig_import_helper _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description) File "c:\programdata\anaconda3\lib\imp.py", line 242, in load_module return load_dynamic(name, filename, file) File "c:\programdata\anaconda3\lib\imp.py", line 342, in load_dynamic return _load(spec) ImportError: DLL load failed: The specified module could not be found.

在处理上述异常的过程中，发生了另一个异常：

无法加载本机TensorFlow运行时。

请参阅https://www.tensorflow.org/install/errors

出于一些常见的原因和解决方案。在请求帮助时，请在此错误消息的上方包含整个堆栈跟踪。

Answer 1

请按照TensorFlow website的说明进行操作。如果您使用的是较低版本，我建议您使用install Tensorflow 2。

您需要从here下载并安装/更新Microsoft Visual C++ 2015-2019 Redistributable (x64)。

如果您正面临任何其他问题，可能的原因是

Python

• 您的CPU不支持instructions

• Your CPU/ is on 32位
• 无法加载位于不同位置/未安装在系统上的库。

请参考windows CPU和GPU的测试构建配置。
