近期刚收到邮件openvino
出了最新的
linux
版本（
l_openvino_toolkit_p_2020.4.287.tgz
），故见猎心喜，试图在树莓派上安装，谁知把树莓派
TF
卡写坏了，估计试用会稍稍暂停几天……
以下是之前TF卡尚好时的实验记录，正文开始：
安装完成后，在/opt/intel/openvino/inference_engine/samples/
目录下有各种例程，我们先拿一个最简单的来试试
NCS2
是否已经安装了吧。
把NCS2
计算棒插在树莓派的某个
USB
接口上。
cd /opt/intel/openvino/deployment_tools/inference_engine/samples/python
进入该目录以后，用ls
命令看看
python
例程有哪些
- pi@raspberrypi:/opt/intel/openvino/deployment_tools/inference_engine/samples/python$ ls
- classification_sample classification_sample_async hello_query_device object_detection_sample_ssd requirements.txt style_transfer_sample
复制代码
用cd
命令进入hello_query_device
，
执行
pi@raspberrypi:/opt/intel/openvino/deployment_tools/inference_engine/samples/python$ cd hello_query_device/
再查看目录下文件，只有一个py
文件。
- pi@raspberrypi:/opt/intel/openvino/deployment_tools/inference_engine/samples/python/hello_query_device$ ls
- hello_query_device.py README.md
复制代码
执行这个文件试试：
- pi@raspberrypi:/opt/intel/openvino/deployment_tools/inference_engine/samples/python/hello_query_device$ python3 hello_query_device.py
- Available devices:

- VPU_MYRIAD_FORCE_RESET: OFF
- VPU_PRINT_RECEIVE_TENSOR_TIME: OFF
- LOG_LEVEL: LOG_NONE
- VPU_HW_STAGES_OPTIMIZATION: ON
复制代码
拔出NCS2
再尝试一次。
- pi@raspberrypi:/opt/intel/openvino/deployment_tools/inference_engine/samples/python/hello_query_device$ python3 hello_query_device.py
- Available devices:
- pi@raspberrypi:/opt/intel/openvino/deployment_tools/inference_engine/samples/python/hello_query_device$
复制代码
可以看到，这次没有找到可用NCS棒。以上是跑最简单的例程，因某些原因，考虑先发出来，后续再补充完善。
