It seems to use `np.empty` to initialize an array with N element where N is the int being coerced.\r\n\r\nGenerally, I would expect that an int or a float would be coerced to a 1-dimensional array with a single element.\r\n\r\n\r\n### Example Code\r\n\r\n```Python\r\nfrom docarray import BaseDoc\r\nfrom docarray.typing import NdArray\r\n\r\nclass MyDoc(BaseDoc):\r\n    arr: NdArray\r\n\r\nMyDoc(arr=10).arr # Undefined behaviour; uninitialized array\r\n\u003e\u003e NdArray([7.17677097e-312, 1.77863633e-322, 0.00000000e+000,\r\n         0.00000000e+000, 5.28555753e+180, 5.98847221e+174,\r\n         5.92957407e-038, 7.42262642e-091, 2.80246406e-032,\r\n                     nan])\r\nMyDoc(arr=10.0).arr # ValidationError\r\n```\r\n\r\nI would expect instead:\r\n\r\n```\r\nMyDoc(arr=10).arr\r\n\u003e\u003e NdArray([10])\r\nMyDoc(arr=10.0).arr\r\n\u003e\u003e NdArray([10.0])\r\n```\r\n\r\n\r\n### Python, DocArray \u0026 OS Version\r\n\r\n```Text\r\nPython 3.11.9\r\ndocarray 0.40.0\r\nWindows 10\r\n```\r\n\r\n\r\n### Affected Components\r\n\r\n- [ ] [Vector Database / Index](https://docs.docarray.org/user_guide/storing/docindex/)\r\n- [X] [Representing](https://docs.docarray.org/user_guide/representing/first_step)\r\n- [ ] [Sending](https://docs.docarray.org/user_guide/sending/first_step/)\r\n- [ ] [storing](https://docs.docarray.org/user_guide/storing/first_step/)\r\n- [ ] [multi modal data type](https://docs.docarray.org/data_types/first_steps/)","author":{"url":"https://github.com/nathanjmcdougall","@type":"Person","name":"nathanjmcdougall"},"datePublished":"2024-12-04T19:48:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/1914/docarray/issues/1914"}
