Unable to load pretrained weights to model.

[Namasivaayam-L]

I have referred these existing issues and still my issue persists: #48 #40 (tried to copy the code from the weights.txt provided in the issue)

I request you guys to take a look.

CODE: from detr_tf.networks.detr import get_detr_model detr = get_detr_model(config, include_top=False, nb_class=10, weights="detr") detr.summary()

ERROR: Load weights from weights/detr/detr.ckpt 2024-01-13 12:06:41.142705: W tensorflow/core/util/tensor_slice_reader.cc:98] Could not open weights/detr/detr.ckpt: DATA_LOSS: not an sstable (bad magic number): perhaps your file is in a different file format and you need to use a different restore operator?

These are the checkpoint files that got downloaded: I even downloaded the detr.ckpt using this link: https://storage.googleapis.com/visualbehavior-publicweights/detr/detr.ckpt

I have all the files as default from the repository except I am using a custom dataset. But obviously it has nothing to do with my problem here. Thank you.

hi, Namasivaayam, can you share the download weights files? the original links seem invalid now. thank you!

I'm not sure, I have it... I'll chk my hdd and let you know by tonight.
