The data type is stored in a special dtype object; for example, in the above two examples we have: In [21]: arr1.dtype Out[21]: dtype('float64') In [22]: arr2.dtype Out[22]: dtype('int64') In addition to np.array, there are a number of other functions for creating new ...
Hi @aniketbote I posted this answer in Stack Overflow: https://stackoverflow.com/questions/66373169/tensorflow-2-object-detection-api-numpy-version-errors/66486051#66486051 I had this same issue: NotImplementedError: Cannot convert a symbolic Tensor (cond_2/strided_slice:0) to a numpy array. ...
Numpy gives up and returns a dtype=object array, which means Python objects and pure Python processing. You don't get the columnar operations or the performance boost. For instance, you might want to say try: nested + 100 except Exception as err: print(type(err), str(err)) # <class ...
