OSError: cannot identify image file

JingyiHu


I have this issue when I try to use prepare_data function. I already have the newest version of pillow. 
I also noticed that the tiff files that I get from the "export training data for deep learning" can not be opened . 
(constantly showing this)
 As fopr the meta data format, I tried labeled tiles, classified tiles, KITTI labels and PASCAL VOC format. None of their output tiff can be opened.

I m wondering how can I fix this? Thank you!

hello dear communities
Thanks for the answers
Please I reinstated arcgis pro I received the following connection problem.

2nd problem with the notebook: it does not accept the training data generated by arcgis pro? How to generate them and in what format ?

Thank you

You can use the following guide to train models on multispectral imagery.

The error in the OP also occurs with the Train Deep learning Model tool in Pro 2.5

When working with multispectral imagery do I need to use Notebook and arcgis.learn as opposed to the tools in pro which will not work with ms imagery?

I'm using ms imagery and had this error. Using imagery_type ='ms' fixed this.

However, data.show_batch() does not return any images in the notebook. Is this an issue for ms imagery?

Thanks

Can you post a sample tile here and the metadata of the tile, it seems that the imagery you are using is multi spectral imagery. You need to convert multi spectral imagery to RGB format with datatype 8-bit unsigned, you can do it so by layer -> right click -> Export Raster and then check render and RGB options while exporting data.

Also we have added experimental support for multi spectral data, you can trigger that by adding imagery_type='ms' kwarg to prepare_data() method. You can directly used you training data this way, you need to have gdal installed in order to use it. if you are using arcgis pro python environment it would be there by default.
