permission error when setting up in read only virtual enviroment and no internet issue

I have installed protenix in a python virtual environment that is shared by a group and is read only so can be managed by the admin. But when users use the virt env it seems protenix needs to write inside it which is odd? ie

`PermissionError: [Errno 13] Permission denied: '/xxxx/software/protenix1.0.8_b_venv/lib/python3.11/site-packages/protenix/model/layer_norm/lock'`

How can this be fixed so the lock is written to say the users scratch area, can that be done using some environment variable before running protenix?

Reproduce the PermissionError in a read-only virtual environment without internet access, using the reported path under protenix/model/layer_norm/lock. Trace what creates or writes that lock and check whether the package exposes an environment setting for relocating it. Done means users can run Protenix without writing into site-packages, with the lock stored in a writable user or scratch location.
