Dear Organizers, For the past week I've been using the same preprocessing Docker (docker.synapse.org/syn8040529/preprocess@sha256:86da5044aabf1cfa5e337fcb65626e2db155aaf1829b0f8d530e4f16472e1717), and I can verify that it exists here (https://www.synapse.org/#!Synapse:syn8050788) and is shared with dmchallengeit as an administrator. It's also currently being used in an active training submission (https://www.synapse.org/#!Synapse:syn8202885). However, when I submit a new training job using this preprocessing Docker to the training express lane I receive the error Your Submission to the Digital Mammography challenge (8211356) encountered an error, which occurred while performing 'docker pull' on your submitted Docker repository image. The message is: Failed trying: docker pull docker.synapse.org/syn8040529/preprocess@sha256:86da5044aabf1cfa5e337fcb65626e2db155aaf1829b0f8d530e4f16472e1717 Could someone please help me to resolve this issue? Thanks!

@DREAMer I'm not sure what's going on here. I am able to submit syn8211174 to the express lane, no problem. The log files are here: https://www.synapse.org/#!Synapse:syn8219433 My best guess is that there was an intermittent problem which has now ended. Would you please try again and update this thread to say whether it worked?
I will have a look. Update: I verified that our system can pull the Docker image: ``` docker pull docker.synapse.org/syn8040529/preprocess@sha256:86da5044aabf1cfa5e337fcb65626e2db155aaf1829b0f8d530e4f16472e1717 sha256:86da5044aabf1cfa5e337fcb65626e2db155aaf1829b0f8d530e4f16472e1717: Pulling from syn8040529/preprocess 45a2e645736c: Already exists 96b4e3d704e6: Pull complete e3c19c56926f: Pull complete 3c022ee9aca3: Pull complete e35bb5141529: Pull complete a863bf4e7efd: Pull complete 85497a34fdfd: Pull complete 0c2a2d04eb49: Pull complete e13aa425bf47: Pull complete c913de2f039a: Pull complete 061a765f8e61: Pull complete 1040ebf25dc6: Pull complete 8c4837b35a3d: Pull complete bdd97784c139: Pull complete ce46f1794c8c: Pull complete cd1add0b8b25: Pull complete 1cf1ac5c9875: Pull complete 4d37a015abc8: Pull complete ffa7ef7f83c0: Pull complete 45bcb2458d2f: Pull complete 0adb3881d9f2: Pull complete 64fc68a510a9: Pull complete 2ef25d38fd25: Pull complete f8815db22d98: Pull complete Digest: sha256:86da5044aabf1cfa5e337fcb65626e2db155aaf1829b0f8d530e4f16472e1717 Status: Downloaded newer image for docker.synapse.org/syn8040529/preprocess@sha256:86da5044aabf1cfa5e337fcb65626e2db155aaf1829b0f8d530e4f16472e1717 ```
Unfortunately this is preventing me from submitting any training jobs. As a test case, I tried submitting the job that is already running on the main training queue (https://www.synapse.org/#!Synapse:syn8202885) to the express lane training queue, and I received the same error message.

Express lane no longer recognizes my preprocessing Docker docker.synapse.org/syn8040529/preprocess page is loading…
