I got a similar error.
AssertionError: expect 202417260 bytes, found 202417264
This issue #802 also mentioned this error.
did you change label? I also have this error
This error arises because of mismatch of configuration file and loaded weight.
Simple way to solve this is to edit self.offset value in loader.py present at darkflow/darkflow/utils/
updated self.offset = old_offset_value + (found_value - expected_value)
And also check that number of classes in cfg file is equal to the number of labels present in labels.txt
1、首先,我们在ubuntu下先用anaconda2(版本是2还是3不影响)安装了tensorflow. 2、darkflow要求的安装环境是Python3,那么把anaconda2里的Python2升级到python3.5就行,Ubuntu系统默认是自带python2.7的,在使用darkflow时,用source activate py35进入Python3.5环境再使用flow命令就行。 3、接下来,你可以在任何地方安装darkflow,但是要在py35环境下安装,换Python环境source activate py35,然后安装好你会看到darkflow的文件夹,这个文件夹没用,在安装darkflow的时候会自动拷贝到anaconda2/envs/py34/lib/python3.5/site-packages/darkflow/utils(我Python3.5命名的时候手抖,弄成了py34),要改的是上述目录下loader.py第121行,把self.offset = 16改成self.offset = 20
@abhishek795jha I got the same error, and changed the self.offset to the calculated number, I can confirm that the error got disappeared, but after training I saw that the model is way off and cannot detect the trained object at all. so I found that this solution is not gonna work. any experience guys?

I had same problem. My calculated value was 820820 and it didn't detect anything.
I changed back classes to same number (in my case it was 80) and downloaded 80 labels. after that the calculated number was 4 and it started detecting.
I didn't have the time to exactly calculate the bytes, but from my experience I can say that it depends on number of filters.

Hi,i want to ask if you solve this problem because i have exactly the same problem as you
updated self.offset = old_offset_value + (found_value - expected_value)=16+769504=769520
and the calasses=5
filtres=50=5(5+5)
AssertionError: expect 44179096 bytes, found 44948600
but i stil have the same pb
any help
@me6ran Didn't happen with my training. Can you describe your data and hyperparameter, if possible
I don't know whether it's a good idea or not. But it works if you comment out that assert statement.
abhishek795jha is right! I solved the problem. http://tn00343140a.pixnet.net/blog/post/299895872-YOLO%E9%81%8B%E8%A1%8Cdarkflow%E6%99%82,%20%E5%87%BA%E7%8F%BEAssertionError:%20expect%20203929404%20bytes,%20found%20203934260
Error :- AssertionError: expect 63184556 bytes, found 63184560
Solution : " ./darkflow/utils/loader.py" at line 121, you will find self.offset= 16 or 20. update to be done : - found 63184560 - expect 63184556 = 4, then add 4 to self.offset = add this 4 (or any other value) diff to 16 or 20 and then run your command again.
Best of Luck, it work for me, hope it may work for you as well, keep helping other.

how can I solve it ?
