_pickle.UnpicklingError: Failed to interpret file '../checkpoint/checkpoint.npy' as a pickle

[nutsintheshell]

I try to evaluate tapir on robotap and davis dataset. however, I got the error：

Traceback (most recent call last):
  File "/home/jishengyin/anaconda3/envs/tapnet/lib/python3.10/site-packages/numpy/lib/npyio.py", line 467, in load
    return pickle.load(fid, **pickle_kwargs)
_pickle.UnpicklingError: invalid load key, '-'.

The above exception was the direct cause of the following exception:

_pickle.UnpicklingError: Failed to interpret file <tensorflow.python.platform.gfile.GFile object at 0x7ff6917b3f70> as a pickle

then I found the error occurs at np.load(path/to/checkpoint_file, allow_pickle=True), the checkpoint file i use is download from readme. could you please solve the problem?

Did you find a solution? Running into the same error.

Did you find a solution? Running into the same error.

I solved the error by changing a model.Notably, the model in readme is a tapnet baseline model, which has a different network structure with tapir model. Therefore, a tapir model in the official colab is needed in checkpoint path when inferencing tapir model.
