predict_new_data_mrc.py runs out of memory

[mhothorn]

When running predict_new_data_mrc.py on even a relatively small number of .mrc files (~150), the following warning pops up

[INFO] Loading up model... [INFO] Loading up test images path ... predict_new_data_mrc.py:46: RuntimeWarning: More than 20 figures have been opened. Figures created through the pyplot interface (matplotlib.pyplot.figure) are retained until explicitly closed and may consume too much memory. (To control this warning, see the rcParam figure.max_open_warning). plt.figure(figsize=(40, 30)) Killed

After the warning, there are still new .jpg files written to CrypSegNat/output/results yet after a while the process fills up all RAM, then all /swap space and then runs out of memory (system has 192 GB or RAM and 92 GB of swap space).

For comparison, predict_new_data_jpg.py on any of the provided test data runs to completion.
