TensorFlow: number of channels of conv1d filter
In TensorFlow there are different convolution layers. Conv1d, Conv2d and Conv3d. the first one is used for one dimensional signals like sounds, the second one is used for images, gray-scale or RGB images and both cases are considered to be two dimensional signals. The last one is used for three dimensional signals like video frames, images as two dimensional signals vary during time. In your case Conv1d is used as one dimensional signal and you can specify the number of filters in the arguments of the method. You can take a look at here and here.
