I would like to implement the following functionality: launching Psychopy when a user sends a request. This is my code.
import datetime
from psychopy import visual, core, event
class Paradigm:
def __init__(self):
self.devices = devices
self.fresh_rate = fresh_rate # 60Hz
self.sti_show_time = sti_show_time # 0.5s
self.frame_num_of_a_sti = int(self.sti_show_time * self.fresh_rate)
self.sti_list = ["paradigms/pic/a.jpg", "paradigms/pic/b.jpg"]
def run(self):
print(self.sti_list)
self.window = visual.Window(allowGUI=False, units="pix", screen=0, fullscr=True, color=[-1, -1, -1])
self.instruction = visual.TextStim(self.window, color=(255, 255, 255), text="Start", height=70, font="simhei")
self.instruction.draw()
self.window.flip()
core.wait(2)
for sti_path in self.sti_list:
self.sti_imag = visual.ImageStim(self.window, image=sti_path, size=self.window.size)
self.window.callOnFlip(self.__add_mark, 1)
for _ in range(self.frame_num_of_a_sti):
self.sti_imag.draw()
self.window.flip()
self.instruction.text = "End"
self.instruction.draw()
self.window.flip()
core.wait(2)
self.window.close()
from flask import Flask
from flask_cors import CORS
from paradigms import Paradigm
para = Paradigm()
app = Flask(__name__)
CORS(app, supports_credentials=True)
@app.route("/paradigm")
def run_paradigm():
para.run()
if __name__ == "__main__":
app.run(host="0.0.0.0", port=19782)
When I run the program and send a request to http://127.0.0.1:19782/paradigm, I encounter the following error:
pyglet.gl.lib.MissingFunctionException: wglChoosePixelFormatARB is not exported by the available OpenGL driver. ARB_pixel_format is required for this functionality.
May I ask how to resolve this?
