my numpy.test hangs here

Test whether equivalent subarray dtypes hash the same. ... ok
Test whether different subarray dtypes hash differently. ... ok
Test some data types that are equal ... ok
Test some more complicated cases that shouldn't be equal ... ok
Test some simple cases that shouldn't be equal ... ok
test_single_subarray (test_dtype.TestSubarray) ... ok
test_einsum_errors (test_einsum.TestEinSum) ... ok
test_einsum_sums_cfloat128 (test_einsum.TestEinSum) ...
