TensorRT: Unable to use any Torch-TensorRT methods

I’m facing this error:

AttributeError: module ‘torch_tensorrt’ has no attribute ‘compile’

I also get this error when I try to use any other method like Input().

This is how I installed Torch-TensorRT: pip install torch-tensorrt -f github.com/NVIDIA/Torch-TensorRT/releases

Code (from official documentation):

import torch_tensorrt

model = model.eval()
compile_settings = {
    "input_shapes": [
        {
            "min": [1, 1, 16, 16],
            "opt": [1, 1, 32, 32],
            "max": [1, 1, 64, 64]
        },
    ],
    "op_precision": torch.half # Run with fp16
}
enabled_precisions = {torch.float, torch.half}

trt_ts_module = torch_tensorrt.compile(model, inputs=compile_settings, enabled_precisions=enabled_precisions) 

Stack Trace:

AttributeError                            Traceback (most recent call last)

     14 enabled_precisions = {torch.float, torch.half}
     15 
---> 16 trt_ts_module = torch_tensorrt.compile(model, inputs=compile_settings, enabled_precisions=enabled_precisions)

AttributeError: module 'torch_tensorrt' has no attribute 'compile'

Please let me know how I can fix this issue.
