Earlier investigations and discussions Using the Seasonic rep, in addition to a several threads about on JonnyGuru, have led me to think that these Seasonic Primary models are delicate to, and do not like, simulated sine wave models and that it is remarkably recommended that only pure sine wave UPS units be used with these power supplies เครื่องสํารองไฟ server if you don't want them to easily shut down once they detect the simulated wave, earning them ineffective.

I figured --format freeze could well be much more sturdy from achievable improvements in future updates than letting pip listing come to a decision the structure. pip freeze also will work!
