{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"np.gradient can not be called with the current pythonnet API","articleBody":"I am reopening an issue which was previously demoted to a question but turns out to be a shortcoming of the pythonnet API. As the discussion #1772 shows, there is no way to successfully call the function numpy.gradient(f, *varargs, axis=None, edge_order=1) as documented here: https://numpy.org/doc/stable/reference/generated/numpy.gradient.html\r\n\r\nHere is an example in python\r\n\r\n```python\r\n\u003e\u003e\u003e import numpy as np\r\n\u003e\u003e\u003e dx=4.0\r\n\u003e\u003e\u003e dy=5.0\r\n\u003e\u003e\u003e zX=[[1,2,3],[4,5,6],[8,9,0]]\r\n\u003e\u003e\u003e np.gradient(zX, dx, dy)\r\n[array([[ 0.75 ,  0.75 ,  0.75 ],\r\n       [ 0.875,  0.875, -0.375],\r\n       [ 1.   ,  1.   , -1.5  ]]), array([[ 0.2,  0.2,  0.2],\r\n       [ 0.2,  0.2,  0.2],\r\n       [ 0.2, -0.8, -1.8]])]\r\n\u003e\u003e\u003e\r\n```\r\n\r\nVarious ways to call the function have been tried in #1772 but none work. This should be considered a bug.","author":{"url":"https://github.com/henon","@type":"Person","name":"henon"},"datePublished":"2022-05-30T18:38:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1804/pythonnet/issues/1804"}
