TensorFlow Library is causing prompt to install Java on Mac OS

[murphye]

There seems to be an issue with how the TensorFlow library from DJL is linked to the JRE that is causing a prompt to install JRE Version 6. This link seems to provide further info on the problem: imagej/pyimagej#10

another workaround is to link to libjli instead of libjvm

Reference info from another issue:

Ok, so this is what I get when I run the executable and hit the /detect endpoint:

I then get a pop up window from Mac OS asking me to install Java 6! Weird, right?

Update: Upon some research, I found this is related to JNI linking to Java libraries in Mac OS and it may require some change to how TensorFlow is linked, but I am not sure. I did not have this issue previously with the TensorFlow native libraries from the TensorFlow project.

I don't have this problem on my Mac, I'm using a fresh Mojave. However, my coworker has the same issue as you. He's mac was upgraded to Mojave from older version.

I am using Catalina (10.15.5) that has been upgraded a few times.

@murphye just want to keep you posted. The author of the JavaCpp is fixing this issue. bytedeco/javacpp#417
I will let you know once the bug is fixed

[frankfliu]

JavaCPP 1.5.4 resolved this issue. We upgraded to javacpp 1.5.4. Will be resolved in DJL 0.8.0 release
