fasta2speclib hangs when multiprocessing is enabled

[RalfG]

Hi Ralf,

I tried the new features today and they seem to work. However, when I set more than one cpu in the config file, the process seems to get stuck in the multiprocessing step at the very beginning. For the tests I used a VM-Server with win10 and python 3.7 (I can not change the version there due to access restrictions). Even with only one cpu the process seems to stop at a step "generated new fontManager".
When I run the very same config file from my desktop computer (python 3.10) multiprocessing works as expected but I have to reduce the chunk-size.

On the computer where the process does not finish, I also have to use a virtual environment in order to call fasta2speclib while on my desktop I installed ms2pip globally and could run both commands directly.

Best,
Juergen

Hi @JB91451,

Thanks for testing and reporting back! The generated new fontManager message could indicate an issue with matplotlib. Is the Windows server a headless environment with only the CLI active and now graphical environment?
Could you provide a list of all package versions used in the environment (e.g. with pip freeze or conda list? A full log might also help me in figuring out the source of the issue.

Thanks!
Ralf

Hi Ralf,

No, the Windows server has a gui and I connect via the remote-desktop tool.

The output from pip freeze is as follows:

E:\JB>E:\JB\ms2pip\venv\Scripts\activate.bat

Digesting proteins... ----------------------------------------   0% -:--:--

At this step the prediction stops without any notice. However, I waited several hours and the computer seems to be idle during the complete time as there is no cpu, I/O or RAM activity from any of the python processes that were started. When I repeat the process with with an altered config file with only one cpu, the digestion and modification assignment works, but ms2pip does not proceed after retention time prediction (or spectrum prediction if DeepLC is disabled):

Please note that the prediction for this first chunk seems to work as the counter that displays ETA, etc. runs down and disapears before the computer turns idle.
