That looks like the right bin. What do you get running the sample code on the following page? |
I ran the sample code in the link, and this is working fine ! I can see the GUI window (ALE Viz) where the "pong" is played and also I could see the printing of the episodes... ====================================================================== Screen Display Active. [Manual Control Mode] 'm' [Slowdown] 'a' [Speedup] 's' [VolumeDown] '[' [VolumeUp] ']'. WARNING: Possibly unsupported ROM: mismatched MD5. Running ROM file... |
Ok, good! There's been a couple of things fixed since DL4J 0.9.1 though, so could you try with 0.9.2-SNAPSHOT and let me know if this still happens? Thanks! |
Hello @saudet !
Please advise further ! |
Ah, you didn't have to build everything from scratch, binaries are available here: In any case, thanks for the log! It makes it clear the issue is this:
Looks like an issue with JavaCV. I should be able to fix this today... |
Actually, I'm unable to reproduce this issue. "crf" is a float value, and setting something like "10.5" works just fine on my machine. Could you try to run the following test and let me know what happens? |
Hello @saudet
Thank you |
You can find a sample pom.xml file for 0.9.2-SNAPSHOT on this branch: It looks like your IDE has trouble loading artifacts from the snapshot server though, that's why JavaCV isn't working there. You'll need to figure out why that is... |
hello @saudet there's some update... now I am getting this error after trying in another PC... please have a look. we tried in the master branch.

@raver119 I'm also getting that stack trace on my machine. Do you know what changed with respect to the compression algorithms? |
Nothing changed AFAIK, but i'm seeing the same issue in nd4j-tests, so i'm going to check & fix that once i'm done with cnn gradients problem. |
ok, so it is an issue with compression, good to know! |
Confirmed fixed, thanks to @raver119! |
