np.load of np.savez impossible to get values back out?

[jensroth-git]

after saving some arrays into a .npz archive like so

Dictionary<string, NDarray> arrays = new Dictionary<string, NDarray>();
arrays["valueOne"] = valueOne;
arrays["valueTwo"] = valueTwo;

np.savez_compressed(filename, null, arrays);

its impossible to get the values back out

var archive = np.load(filename);

var valueOne = archive["valueOne"];
var valueTwo = archive["valueTwo"];

it just results in a System.ArgumentException: 'Invalid slice notation'

Can you give a a similar python code so I can test and compare?

[jensroth-git]

test_array = np.random.rand(3, 2)
test_vector = np.random.rand(4)
np.savez_compressed('/tmp/123', a=test_array, b=test_vector)
loaded = np.load('/tmp/123.npz')
print(np.array_equal(test_array, loaded['a']))
print(np.array_equal(test_vector, loaded['b']))

This is not a fix but a workaround

        [TestMethod]
        public async Task IssueByMrCOrrupted()
        {
            Dictionary<string, NDarray> arrays = new Dictionary<string, NDarray>();
            arrays["a"] = np.arange(6).reshape(2, 3);
            arrays["b"] = np.arange(3);

            var filename = Path.Combine(Path.GetTempPath(), "test.npz");
            np.savez_compressed(filename, null, arrays);
            var archive = np.load(filename);
            Console.WriteLine(archive.repr);
            var a = new NDarray( archive.PyObject["a"]);
            var b = new NDarray( archive.PyObject["b"]);
            Console.WriteLine(a.repr);
            Console.WriteLine(b.repr);
        }
