Can’t Run a Coral EdgeTPU classification model with TFLite API #22

Closed ssghost closed 4 years ago

ssghost commented 4 years ago

I am trying to apply the tutorial of coral USB accelerator with MacOS 10.15. The tutorial link : Get started with the USB Accelerator

Everything is successfully done until the last step "Run the image classifier with the bird photo (shown in figure 1)"

I copied the code to my terminal: python3 classify_image.py \ --model models/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite \ --labels models/inat_bird_labels.txt \ --input images/parrot.jpg

My terminal returns this error information: Traceback (most recent call last): File "classify_image.py", line 122, in <module> main() File "classify_image.py", line 99, in main interpreter = make_interpreter(args.model) File "classify_image.py", line 73, in make_interpreter {'device': device[0]} if device else {}) File "/Users/xxx/anaconda3/lib/python3.6/site-packages/tflite_runtime/interpreter.py", line 204, in __init__ model_path, self._custom_op_registerers)) SystemError: <built-in function InterpreterWrapper_CreateWrapperCPPFromFile> returned a result with an error set

How should I fix it?

Can you share the outputs of these commands?

python3 -c 'print(__import__("tflite_runtime").__git_version__)'
python3 -c "from ctypes import *; cdll.LoadLibrary('libedgetpu.so.1.0'); print('success')" 
md5sum /usr/local/lib/libedgetpu.1.0.dylib

python3 -c 'print(__import__("tflite_runtime").__git_version__)' '0.6.0-76902-gd855adfc5a' python3 -c "from ctypes import *; cdll.LoadLibrary('libedgetpu.so.1.0'); print('success')" OSError: dlopen(libedgetpu.so.1.0, 6): image not found md5sum /usr/local/lib/libedgetpu.1.0.dylib a8a47d9dc537bd56c77cc5c7cb4e6aa6 /usr/local/lib/libedgetpu.1.0.dylib

Although I still don't know the reason, today when I run the command again on the same computer, it worked well as the webpage described. So please close this Issue thread.

@ssghost Ahh, I was trying to check if the correct version of /usr/local/lib/libedgetpu.1.0.dylib was installed on our system. But from your outputs, everything looks good :)
