Saving model error

[yossadh]

I am going through the tutorial and everything works perfectly except when saving the model (Tutorial 03, 04). Here's the error: With cluster.save('nb4.pyemma', model_name='ala2tica_cluster', overwrite=True)

~/anaconda3/lib/python3.7/site-packages/h5py/_hl/files.py in make_fid(name, mode, userblock_size, fapl, fcpl, swmr)
    188         if swmr and swmr_support:
    189             flags |= h5f.ACC_SWMR_READ
--> 190         fid = h5f.open(name, flags, fapl=fapl)
    191     elif mode == 'r+':
    192         fid = h5f.open(name, h5f.ACC_RDWR, fapl=fapl)

PyEMMA 2.5.7 Output of conda list: conda_list.txt

Here's a quick checklist in what to include:

• [v] Include a detailed description of the bug or suggestion
• [v] pip list or conda list of the environment you are using (please attach a txt file to the issue).
• [v] PyEMMA version and operating system versions
• [v] Minimal example if possible, a Python script, zipped input data (if not too large)

This looks like a for some reason corrupted file. Have you tried changing the filename (like nb4_2.pyemma')?

That's what I gather too from googling, but this is saving file, not reading... I tried anyway with different filenames, still same error. That swmr flag seems to be the problem.

Edit: For a workaround, saving directly with pickle.dump works ok
