i installed torch with
pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu

as i found somewhere say nightly support 3.11
now i'm wondering it's torch problem or easyocr problem
if someone know what pip to run for python 3.11, if even it's supported as i can't find what version it supports
i tried different torch version, disinstalled numpy to see if
pip install easyocr

resolve it self but nothing
i also tried
pip install git+https://github.com/JaidedAI/EasyOCR.git

and
PS C:\Users\lenovo\Documents\python\My Heroes> pip install numpy==1.21.2

with this output

edit1: after someone suggested i runned by unistall my torch version first
pip install --pre torch -f https://download.pytorch.org/whl/nightly/cpu/torch_nightly.html

that's the pip show torch output

unfortunatly after running pip install easyocr the same error still reproduce, so it let me think it may be a easyOCR 3.11 support problem?

Answer: You are having trouble finding a version of numpy that matches the required version (numpy==1.21.2). (the error is indicating that one of the dependencies required by the EasyOCR library is the specific version of NumPy)
Try to install numpy version 1.21.2 separately using pip install numpy==1.21.2 and then try installing easyocr again using pip install easyocr.
