Read Troubleshoot

[x] I admit that I have read the Troubleshoot before making this issue.

Describe the problem I started fooocus on cloud computing linux with CPU. I used the ['--share', '--always-cpu', '--attention-split'] flags to use only the CPU, but the error regarding lzma appeared:

  File "/home/<User>/Fooocus/fooocus_env/lib/python3.10/site-packages/torchvision/datasets/utils.py", line 6, in <module>
    import lzma
  File "/usr/local/lib/python3.10/lzma.py", line 27, in <module>
    from _lzma import *
ModuleNotFoundError: No module named '_lzma'

I currently use Debian GNU/Linux 11 (bullseye).

Solution

The only solution I found is pip install backports.lzma && apt-get install -y liblzma-dev and was to modify the python libraries fooocus_env/lib/python3.10/site-packages/torchvision/datasets/utils.py:

try:
    import lzma
except ImportError:
    from backports import lzma

I setup using python-venev. I encountered other problems with python, but it was enough to follow https://github.com/lllyasviel/Fooocus/issues/1074#issuecomment-1872577606 issues.

ofc! this is the FULL log with the described problem regarding _lzma. The only thing you notice from the web page is that it stays stuck at Waiting for task to start....

I don't know what ´_lzma iss used for, but you can also try and just install it.

As this is already the solution you've mentioned this issue can be closed and will be referenced to on further issues of the same kind. Thank you!
