Image 2008_001335.jpg not indexed error

[jxlin]

Thank you very much for nice work! I try to follow the README.md to search for a similar image to an input image, the first step to index images under the dataset folder works well, but the second step generates the "Image 2008_001335.jpg not indexed" error, as shown in the attached picture. My goal is to search for the most similar image under the dataset folder to an arbitrary input image, could you please help me reach this goal? Thanks again
