Describe the bug

Code

import torch
import nemo.collections.asr as nemo_asr

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = nemo_asr.models.EncDecCTCModel.restore_from(
    restore_path="/Users/user/Downloads/ai4b_indicConformer_kok.nemo"
)
model.freeze()
model = model.to(device)

AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
