Assertion `NPY_CHECK_GIL_HELD()' failed.
Getting this error when trying to display any channel:
hiq@hiq-ws1 ~ $ LC_ALL=C ndscope G8:FE1-ADC_FILTER_0_IN1
[...]
8:FE1-ADC_FILTER_0_IN1: numpy/core/src/multiarray/alloc.c:70: _npy_alloc_cache: Assertion `NPY_CHECK_GIL_HELD()' failed.
Note the missing "G" in the channel name of the error message. ndscope version is 0.7.9, numpy (if that matters) is 1.18.3. Using numpy 1.19.1 instead gives this slightly different error message:
8:FE1-ADC_FILTER_0_IN1: numpy/core/src/multiarray/alloc.c:91: _npy_alloc_cache: Assertion `PyGILState_Check()' failed.
