Aaaahg! the dreaded ESP-01 
You should do some careful reading about what you need to do to put these into flash mode, it’s quite fiddly.
Also, some of the cheap ESP-01 to USB programming adapters aren’t made correctly. They have a flash button that needs to be pressed when plugging-in the adapter, but the button isn’t wired correctly, so it doesn’t work.

I’d save yourself a lot of hassle and buy a Wemos D1 Mini. Better still, order a pack of 10
