Maskrcnn-benchmark: COCODemo object: pickle data was truncated

[BelhalK]

🐛 Bug

The creation of the COCODemo object is interrupted with the following error message

pickle data was truncated

The progression bar stops at around 70%

To Reproduce

The following code reproduces the error

from maskrcnn_benchmark.config import cfg
from predictor import COCODemo
config_file = "../configs/caffe2/e2e_mask_rcnn_R_50_FPN_1x_caffe2.yaml"

# update the config options with the config file
cfg.merge_from_file(config_file)
# manual override some options
cfg.merge_from_list(["MODEL.DEVICE", "cpu"])
coco_demo = COCODemo(
    cfg,
    min_image_size=800,
    confidence_threshold=0.7,
)

Expected behavior

The CocoDemo Object is supposed to load and be created.

Additional context

Looks like the model downloading didn't work as expected (network problem maybe?).
Can you delete the file that starts with a _ in ~/.torch/models/ and try running it again?
It should work if the download is not interrupted.

As this seems to be a network issue, I'm closing this issue, but let me know if you still have issues.

Indeed it works.
Sorry about that.
Have a good day

Great, glad to know that it works now!

can you tell me where is the file? I can't find it.
