  • Mobile device (e.g. iPhone 8, Pixel 2, Samsung Galaxy) if the issue happens on mobile device:
  • TensorFlow.js installed from (npm or script link): script link
  • TensorFlow.js version (use command below): 4.2.0

Describe the current behavior

        var x = [[1330577513.2161741,-1921359847.6188612,-1794069072.8702362]]
        var filter = [[[109025596.11600018,-1264649391.5241914],[-1340376825.4206982,-1400198575.229503],[1509516682.11521,1309531766.3778458]]]
        var stride = 3
        var pad = 0
        var dataFormat = "NWC"
        var dilation = 1
        var dimRoundingMode = "floor"
        var result = tf.conv1d(x, filter,stride,pad,dataFormat,dilation,dimRoundingMode)
        console.log("the result of ", tf.getBackend(), "is:\n" );
        result.print();

The output results are inconsistent when executing the above code snippets on different backends.
Output：

Describe the expected behavior

The output should be consistent across all backends.
