Hi,

Yesterday i already posted my question in google dev group but dont have any people reply me

https://groups.google.com/g/doubango-ai/c/w3olFB27IXE

So, i ask again from you

1. I get asterisk from the result, is it after i purchase and put the token then it will be working fine? Below i put the sample result that i get
   

{"duration":83,"frame_id":4,"plates":[{"car":{"confidence":99.99993,"warpedBox":[52.12874,37.58181,577.5889,37.58181,577.5889,388.8009,52.12874,388.8009]},"confidences":[89.80666,99.11021,91.09354,89.83463,90.02847,90.06487,90.33405,90.2272,89.80666],"text":"VGX420*","warpedBox":[338.9168,251.9765,461.4555,251.9765,461.4555,293.9014,338.9168,293.9014]}]}

The last digit is obfuscated (*) because there is no license data. This has nothing to do with accuracy. We hide the last number. You need a license to remove the restriction.

2. I saw that there has models folder under assets directory, so is it you guys will give me new file in order to increase accuracy from time to time?
   

Quote from https://www.doubango.org/pricing.html: "The rights to get the new updates is tied to the support account but for now we don't enforce this rule. We let the license owners get the new updates for free."

2. 
   

3. I tried to run in linux (centos 7-docker) environment, after i copied the .so required, then i faced this issue will starting, is it only able to run in ubuntu?
   

Caused by: java.lang.UnsatisfiedLinkError: /data/carpark/aplr/libultimate_alpr-sdk.so: libtensorflow.so.1: cannot open shared object file: No such file or directory

Where can i get this libtensorflow.so.1? I tried to download from online & also from the groups post but still not working

Quote from https://github.com/DoubangoTelecom/ultimateALPR-SDK/tree/master/samples/java/recognizer#examples: "Before trying to run the program you'll need to download libtensorflow.so as explained here"

4. I see the Gold package gt provide 2 month technical support, but what it means?

Hi,

Thanks for your interest in our product.

The best way to ask technical questions is via our dev-group: https://groups.google.com/g/doubango-ai

We don't use WhatsApp.

Hi, how about question 4?

[Mamadou DIOP]

Gold is direct technical support via email instead of dev-group (best effort). There is also rights to get updates for new code, but as said in 2, everyone can get updates for free for now.

[Mamadou DIOP]

ok, thanks you.

And i still not able to import the libtensorflow.so.1, could you help me? i already follow the github and download from https://doubango.org/deep_learning/libtensorflow_r1.14_cpu_linux_x86-64.tar.gz

[Mamadou DIOP]

You should read https://github.com/DoubangoTelecom/ultimateALPR-SDK/tree/master/samples/java/recognizer#examples

and note how LD_LIBRARY path is used to add the folder you're listing to the system path.

Yout issue isn't related to our product. You would have same issue with any other lib if you don't reference the 3rd parties. You should take take to read Java documentation.

I am follow this one to add into my java program

https://github.com/DoubangoTelecom/ultimateALPR-SDK/blob/master/samples/java/recognizer/Recognizer.java

it is working fine when i running in window, but after i try to run on docker in CentOS Linux release 8.5.2111 (x86_64) it has show several issue due to i less import some of your .so file, after importing all .so file, then in the end i get this tensorflow issue, then i had based on your previous advice to add in the libtensorflow.so.

I didn't use LD_LIBRARY to set the path is because my java program already set load the libultimate_alpr-sdk.so from my folder, all the so files that come from your github are put in the same folder too.
