Code worked once, now core dumped #10

Closed zabop closed 5 years ago

zabop commented 5 years ago

I had a code which worked, now it does not, and I think it has to do something with the fortran part of the package. It is described here: https://stackoverflow.com/questions/52392709/code-worked-once-now-core-dumped-from-nufft-algorithm-what-went-wrong Is this only me, or is it a general issue? Cheers:)

I also received this error with the above ^ script.py: python3 script.py *** Error in `python3': double free or corruption (out): 0x00000000030ce6e0 *** Details: https://pastebin.com/E6qZLF9y

I found some information about this bug here: https://github.com/tensorflow/tensorflow/issues/6968 And if I use this workaround ( https://github.com/tensorflow/tensorflow/issues/6968#issuecomment-273959067 ), apt install libtcmalloc-minimal4, export LD_PRELOAD="/usr/lib/libtcmalloc_minimal.so.4", then (running the script) I receive a more verbose explanation: Traceback (most recent call last): File "script.py", line 14, in <module> max_index = np.abs(ft[1:]).tolist().index(max_value) ValueError: nan is not in list

Change the line specifying f tof=np.linspace(0.95,1.05,10000), and it'll work
