AVX support was added to some CPUs starting in 2011 - and not even all. So, it's conceivable that your CPU doesn't meet the requirements. You can check your CPU:

sudo docker run -it jjanzic/docker-python3-opencv grep avx /proc/cpuinfo

If your CPU supports the AVX instruction, you'll get one or more lines that looks something like this:

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht pbe syscall nx pdpe1gb lm constant_tsc rep_good nopl xtopology nonstop_tsc eagerfpu pni pclmulqdq dtes64 ds_cpl ssse3 sdbg fma cx16 xtpr pcid sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand hypervisor lahf_lm abm kaiser fsgsbase bmi1 avx2 bmi2 erms xsaveopt arat

If you don't get one or more of these lines, then your CPU isn't supported. Basically.
