I have met the same problem. Do you solve it ?

I find the same problem in ORB2 Issue #903. It seems like there was an invisible character '\r ' in the timestamp file. I create a new blank MH01.txt. Then copy all from /EuRoC_TimeStamps/MH01.txt to my MH01.txt and replace the original one. It solved!

@skewed666 Did you solve your problem? I had the exact same issue, and it originated from a very stupid problem: The Machine Hall Dataset one can download is called "MH_01_easy", so when I renamed it, I renamed it to "MH_01" instead of "MH01", which is why the images couldn't be found.

@yuguanfeng solution solved for me. Thanks! I used notepad++ to extract only the useful characters.

I also met the same problem, you can try to check the path again,for example,~/Datasets/EuRoc/MH01,should be ./Datasets/EuRoc/MH01？Double-check again
