Missing np.tile? #397

Open QadiymStewart opened 4 years ago

QadiymStewart commented 4 years ago

Is np.tile implemented in this library as of yet?

simonbuehler commented 4 years ago

hi,

bumped into the same issue, is there a workaround for something like np.tile(center, (1, 1, 2 * num_anchors)); or maybe even better a working tile implementation?

Switched to https://github.com/Quansight-Labs/numpy.net

@QadiymStewart thanks for your reply, a pity that tensorflow.net depends on NumSharp so i can't switch :/
@Oceania2018 are there plans to implement this like inNumpyDotNet/shape_base.cs ?

Oceania2018 commented 4 years ago

@simonbuehler Try to use the built-in functions of tensorflow. https://www.tensorflow.org/api_docs/python/tf/tile

simonbuehler commented 4 years ago

is there already a nuget with a Tensor -> NDarray method?

Oceania2018 commented 4 years ago

@simonbuehler You can create tensor directly from Tensor -> NDArray and vice verse.

just for info, unfortunatly var center_tiled = tf.tile(temp , temp2); throws a NullReferenceException guess this is a TensorFlow.NET issue, nevertheless a numsharp implementation would be awesome!

@Oceania2018 hi, are there any chances that np.tile could be implemented?
