Missing libpython3.6m.so in Linux v1.0.1

[mfaytak]

From a fresh download of v1.0.1 on my device (running Ubuntu16.04 xenial). Test running /bin/mfa_align to see usage instructions results in the following error message.

[1695] Error loading Python lib '/opt/montreal-forced-aligner/lib/libpython3.6m.so': dlopen: /opt/montreal-forced-aligner/lib/libpython3.6m.so: cannot open shared object file: No such file or directory).

In case it's informative, running mfa_train_g2p and mfa_generate_dictionary generates the same error, but running mfa_train_and_align does not.

Thanks for an otherwise great piece of software (the Windows version of v1.0.1 is great),

Same here. All I had to do was ln -s lib/libpython3.6m.so.1.0 lib/libpython3.6m.so.

@sailordiary Creating a link to the handle of the missing file actually did not work in my case. However, copying the contents of lib/libpython3.6m.so.1.0 to lib/libpython3.6m.so does seem to fix the problem.

Thanks for the workarounds! I think this is probably caused by having upgraded the freezing package. I'll try to get this fixed up for the release soon!

After copying as you suggested, my conda just broken and can not activate. Do you know how to undo this copy and fix the conda?

Hey,
To all those who are unable to resolve this issue in linux
Shift to the windows version, I can confirm that it works perfectly there without this issue. This seems to be just a linux based issue.

me too,if you solved plz give answer!

[SachinG007]

As I mentioned in my previous comment, this is a known issue with the python version of the Montreal Forced Aligner. Try using the windows version of the same and it will work perfectly.

@sybilWsybil @Luzeru @romadomaa I also originally attempted to make the symlink with ln -s as in the earlier answer. This also didn't fix the issue for me. So from a fresh install I literally copied the file libpython3.6m.so.1.0 to libpython3.6m.so - in other words, just give the MFA the file it is looking for. To be clear, that would be cp [pathtofile]/lib/libpython3.6m.so.1.0 [pathtofile]/lib/libpython3.6m.so.

@Luzeru I also noticed - there is an extra .. in your first file path in the ln -s command, suggesting you are not creating the symlink from the right directory - if you need to .. back one level then the link to ./libpython3.6m.so isn't going to be in the same directory as the other file. Not sure if this relates to your and the others' newer issue (the core dumped message).

in your case

cd /home/baby/weishu/code/Montreal-Forced-Aligner-1.0.1/dist/montreal-forced-aligner/lib
cp [path/to/your/libpython3.7m.so.1.0]  .
ln -s libpython3.7m.so.1.0 libpython3.7m.so.1
ln -s libpython3.7m.so.1.0 libpython3.7m.so
./align

Do not run soft link bin/mfa_align, run lib/align instead

@zhouyangnk Thank you so much

[HoldON-tts]

hey, look carefully in the lib path, maybe you just need the following command line to change the file_name

cp libpython3.6m.so.1.0 -r libpython3.6m.so

copy and rename it.
