First of all, you need add:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The problem still exists.

Hi,
I guess you are using the previous version of the code in this repo, have you tried to update the tf-interpreter version? Maybe it is too old

I am using the latest version of the tflite branch. I both tried with several versions of tensorflow-lite including nightly. tf-interpreter is a part of tensorflow-lite, right?

[FilippoAleotti]

And about the code? I guess you are you using the android code from the previous version, but are you loading the new or the old checkpoint?

[watchman94]

Yes, The master branch can work. Filippo Aleotti <notifications@github.com> 于2020年8月25日周二 下午11:07写道：

I mean, in the tflite branch which model are you trying to load? The pydnet++ (the one included in that branch) or the new one?

[onurays]

The tflite branch has already its own model. I both used it and tried to generate a new one with the script in the branch. I also tried to use scripts under the master branch and I did all of these tests with different tensorflow versions. Are you planning to update the model and scripts in this branch?
