Error in `python3.5': corrupted size vs. prev_size when running python3.5 synthesis.py

[lightsailpro]

I was able to run the "python3.5 synthesis.py ....". But it generated an error at the end each time.

.............................. Finished! Check out ./output for generated audio samples.

*** Error in `python3.5': corrupted size vs. prev_size: 0x0000000001682bd0 *** Aborted (core dumped)

By commenting out the following code section, the error went way. Not sure if it is related to the setting "backend : Agg" I set for matplot.

       dst_alignment_path = join(
            dst_dir, "{}_{}{}_alignment.png".format(idx, checkpoint_name,
                                                    file_name_suffix))
        plot_alignment(alignment.T, dst_alignment_path,
                       info="{}, {}".format(hparams.builder, basename(checkpoint_path)))

There is another bug when running on Python 3.5 ubuntu 14.04. Sometime the 1st run causes segment fault. It usually runs fine 2nd time. See below for example run: #1st run failed python3.5 synthesis.py --hparams="builder=deepvoice3,preset=deepvoice3_ljspeech" models/20171213_deepvoice3_checkpoint_step000210000.pth ./text_list.txt ./output

Segmentation fault (core dumped)

#2nd run, succeeded python3.5 synthesis.py --hparams="builder=deepvoice3,preset=deepvoice3_ljspeech" models/20171213_deepvoice3_checkpoint_step000210000.pth ./text_list.txt ./output

Command line args: {'--checkpoint-postnet': None, '--checkpoint-seq2seq': None, '--file-name-suffix': '', '--help': False,

Occasionally also got this exception at the end of a run: Exception ignored in: <function WeakValueDictionary.init..remove at 0x7f3205a797b8> Traceback (most recent call last): File "/usr/lib/python3.5/weakref.py", line 117, in remove TypeError: 'NoneType' object is not callable
