I am new to Coral TPU. I am using this USB accelerator and trying to get the initial demo run and monitor the inference time. But, I am getting this error. Please let me know if you have any leads? Thanks in advance guys! :)

hjonnala commented 3 years ago

Hi, Let me know your python version. please uninstall tflite_runtime and pycoral install it from this whl files using pip: https://github.com/google-coral/pycoral/releases

AkkiSony commented 3 years ago

Hi @hjonnala, My current python version is 3.6.9.

I am just unsure which .whl file, I have to install. As I am using a virtual machine (linux) on host(windows), I am sure that I have to use linux_x86-64. However, I am not sure about cp35, cp36. Can you please elaborate to me what does this indicate? Thank you for responding! :)

manoj7410 commented 3 years ago

cp35 means that it is compatible with Python3.5 and cp36 means that it is compatible with Python3.6.

AkkiSony commented 3 years ago

Thank you for the clarity! :) @manoj7410

coral-TPU-error1

I installed pycoral and tflite_runtime as per your suggestion. Since I have python version 3.6, I installed the corresponding cp36.

Now, I am getting the following error when I run the demo as shown on the coral page. Please let me know what am I missing.

manoj7410 commented 3 years ago

@AkkiSony Are you able to see the USB Accelerator(Named : Global chip) in the output of the command:

AkkiSony commented 3 years ago

coral-TPU-error3

That's my output! Is it also called Google Inc ?

AkkiSony commented 3 years ago

I could find Gloabal UniChip after unplugging and plugging the USB device again. However, I still have the "ValueError: Failed to load delegate from libedgetpu.so.1" error.

Please find the attached screenshot. coral-TPU-error4

AkkiSony commented 3 years ago

One thing that I noticed is that when I execute the classify_image.py, I can visualize the Global UniChip for few seconds, and after sometime it dissapears! :/ After I get this Value error, when I do

Do you have any suggestions?

manoj7410 commented 3 years ago

So this is how the USB Accelerator works, while connecting the device with your host PC, the Vendor name will appear as : Global Chip Inc. but once you run the first inference, the Vendor name will change to 'Google Inc'. VM is not officially supported by Coral because of various challenges related to IO operations and restrictions.

AkkiSony commented 3 years ago

Sometimes it works. But it says "Aborted (core dumped)". Can you please let me know why? This is an example code as I said before. coral-TPU-error5

AkkiSony commented 3 years ago

Hi, As VM is not supported, I decided to shift to Windows(host) installation. During the initial steps of installation. https://coral.ai/docs/accelerator/get-started/#runtime-on-windows When I run the .bat file, a command prompt opens and closes every second. This cycle keeps going on. Can you please tell me why am I facing this strange issue?

manoj7410 commented 3 years ago

@AkkiSony Do you see any error too? I haven't seen this behavior yet.

AkkiSony commented 3 years ago

I do not see any error. The cmd prompt opens and closes within one second. And this keep going on until I close the window. It just keeps flashing in and out! :/ Can you try installing using that .bat file and let me know if your're facing the same issue?

manoj7410 commented 3 years ago

@hjonnala Do you have a Windows machine available with you? If yes, then can you please try to execute the instructions given at: https://coral.ai/docs/accelerator/get-started/#runtime-on-windows ?

AkkiSony commented 3 years ago

Hi, Sorry it was organisational issue. After I clicked on the .bat file, it required me to enter the admin right. After entering the admin pwd, things worked fine. Now I am able to install them! :)

AkkiSony commented 3 years ago

Just a small question with the installation procedure for windows system. Should this be done in an Anaconda platform? If not, then should we create a virtual enviroment and then install the packages like tensorflow_lite and pycoral?

hjonnala commented 3 years ago

It should be fine in an Anaconda platform too. Let us know if you are facing any issues.

AkkiSony commented 3 years ago

I am facing this issue when I execute "bash examples/install_requirements.sh classify_image.py" Note: I am in Anaconda platform. coral-TPU-error6

hjonnala commented 3 years ago

please install git bash and try to run those commands.

For instructions please refer to: https://coral.ai/docs/dev-board/get-started/#other-windows-requirements

AkkiSony commented 3 years ago

Thanks for the answer. That helped me. But since I have to execute these commands on git bash, why do I require Anaconda?

Please find the output of the command below. Still the test_data directory remain empty! :(

$ bash examples/install_requirements.sh classify_image.py NOT FOUND: mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite NOT FOUND: mobilenet_v2_1.0_224_inat_bird_quant.tflite NOT FOUND: inat_bird_labels.txt NOT FOUND: parrot.jpg

I am stil not sure why couldn't it download the model. label.txt and the image!

hemanthreddyjonnala commented 3 years ago

I am not sure why the files are not getting downloaded.

Script trying to download files form this link, can you check if this link working or not on your Machine: https://github.com/google-coral/test_data/raw/master/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite

bash_examples

AkkiSony commented 3 years ago

The link works fine. It downloaded the model as soon as I clicked it! But why is it not possible through the script? Do I have to install pycoral and edgetpu only from.whl files?

hemanthreddyjonnala commented 3 years ago

Please install edgetpu runtime from zip file (https://coral.ai/docs/accelerator/get-started#runtime-on-windows)

tflite_runtime and pycoral from .whl files

can you try these two commands on bash terminal.

curl -Lso /dev/null -w "%{http_code}" "https://github.com/google-coral/test_data/raw/master/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite"

curl -OL "https://github.com/google-coral/test_data/raw/master/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite"

AkkiSony commented 3 years ago

The two commands on bash terminal gave me the output as follows.

coral-TPU-error-7

hjonnala commented 3 years ago

the first should give 200 response. Please check with your organization team why the connection is refused.

AkkiSony commented 3 years ago

Please find the below screenshot. When I execute that command, neither am I getting output nor any error. :/ coral-TPU-error-8

AkkiSony commented 3 years ago

tflite_runtime and pycoral from .whl files

For this, do we have to create a virtual environment and then install? I am sorry, I have not worked much on windows side.

hjonnala commented 3 years ago

virtual environment or without virtual environment both would work..

hjonnala commented 3 years ago

Please find the below screenshot. When I execute that command, neither am I getting output nor any error. :/ coral-TPU-error-8

can you try these two commands:

python3 examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg

py examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg

AkkiSony commented 3 years ago

@hjonnala Thank you for your reply!

virtual environment or without virtual environment both would work..

Can you please give me a short description how to install .whl files on windows side. I am confused because, on Anaconda platform we can create virtual environment and then instal using pip command. But on Git bash, since there is no pip installed, how do we do it? Can you please guide me with a short description?

hemanthreddyjonnala commented 3 years ago

For pip installations You can use anaconda platform as you described above.

On bash run pip install command with python executable. sample command: c:\pyhton36\python.exe -m pip install numpy

AkkiSony commented 3 years ago

Thank you for your input. It really helped alot. I added the path of Python and Pip to my PATH variable.

But when I try to install the .whl files, I am getting these error. coral-TPU-error-9

It says, "Not supported wheel on this platform" :/

hjonnala commented 3 years ago

You are trying install linux versions.

we have new releases. Please install

edgetpu runtime form this (https://github.com/google-coral/libedgetpu/releases/download/release-grouper/edgetpu_runtime_20210726.zip) and tflite runtime and pycoral from below: if your python version is 3.6 for windows:

pip3 install https://github.com/google-coral/pycoral/releases/download/v2.0.0/tflite_runtime-2.5.0.post1-cp36-cp36m-win_amd64.whl
pip3 install https://github.com/google-coral/pycoral/releases/download/v2.0.0/pycoral-2.0.0-cp36-cp36m-win_amd64.whl
AkkiSony commented 3 years ago

Thank you for making me notice that I was installing the linux version. I am sorry for that! :)

Whe I try to run the example, I am getting the below error. Please can you guide me for the same? :) I thank you in advance for your time! Do you think its some installation issue? coral-TPU-error-10

hjonnala commented 3 years ago

Hi, which python version version you are using?

I think it's due to pillow version. can you try this

pip uninstall pillow pip install Pillow==8.3.1

AkkiSony commented 3 years ago

Hello @hjonnala , $ python --version Python 3.8.8

I uninstalled Pillow version 8.2. While installing Pillow==8.3.1, I am getting an error

coral-TPU-error-11

hjonnala commented 3 years ago

can you create new virtual environment and try this command.

python3 -m pip install --index-url https://google-coral.github.io/py-repo/ --extra-index-url=https://pypi.python.org/simple pycoral

if python3 not working try: py -m pip install --index-url https://google-coral.github.io/py-repo/ --extra-index-url=https://pypi.python.org/simple pycoral

AkkiSony commented 3 years ago

I activated the default virtual environment "base". After executing the above command, I am getting the same error as above.

I even tried to add them to trusted hosts. python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

Yet the same error as the image attached in the previous thread! :(

hjonnala commented 3 years ago

Instead of base can you please create new virtual environment and paste the entire output of python3 -m pip install --index-url https://google-coral.github.io/py-repo/ --extra-index-url=https://pypi.python.org/simple pycoral

AkkiSony commented 3 years ago

I tried these commands after creating a new virtual environment using conda platform, yet I have these errors.

I even added proxy by using set http_proxy=..... set https_proxy=....

AkkiSony commented 3 years ago

I solved the above error by adding an extra command. Hope it helps someone with the same error. :)

pip install pycoral-1.0.1-cp38-cp38-win_amd64.whl -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

AkkiSony commented 3 years ago

I am now getting segmentation fault as the output for both the statements. Can you help me solve the issue please?

I uninstalled and installed new version of edge_tpu. Later I also uninstalled old version of pycoral and tflite_runtinme and re-installed latest version fo pycoral and tflite_runtime. Apart from this I haven't made any changes. Can you please have a look.

bash examples/install_requirements.sh classify_image.py This statement gives me module not found error! :/
