ModuleNotFoundError: No module named ‘nvidia‘_modulenotfounderror: no module named 'nvidia

自TensorFlow 2.12起，TensorFlow不再有专门的GPU版本，TensorFlow团队发布了一个Install TensorFlow with Pip的安装指南，在安装TensorFlow 12.0或以上版本之前，TensorFlow团队要求执行如下命令，但执行后却出现ModuleNotFoundError: No module named 'nvidia'的错误。这个问题目前在网上还没有解决办法。

Install TensorFlow with pip


https://www.tensorflow.org/install/pip

$ mkdir -p $CONDA_PREFIX/etc/conda/activate.d

$ echo 'CUDNN_PATH=$(dirname $(python -c "import nvidia.cudnn;print(nvidia.cudnn.__file__)"))' >> $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh

$ echo 'export LD_LIBRARY_PATH=$CONDA_PREFIX/lib/:$CUDNN_PATH/lib:$LD_LIBRARY_PATH' >> $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh

$ source $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh

Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'nvidia'
dirname: missing operand
Try 'dirname --help' for more information.

另一种情况是在安装了TensorFlow 2.12或以上版本后只能识别CPU、不能识别GPU的情形，目前网上查到的一个TensorFlow论坛链接，仅供参考：
