PsychoPy脚本运行触发GLException错误求助（附复现代码）

问题描述 #

在Windows 10/11系统上使用独立版PsychoPy-2023.2.3的Coder运行实验脚本时，反复触发pyglet.gl.lib.GLException: b'invalid value'错误。脚本用于测试被试回忆不同音节数无意义单词的暴露时长，两台不同电脑均复现该问题。

复现代码 #

from psychopy import visual, core, event, data, gui
import pandas as pd

# Use a dialog box to get participant number
dlg = gui.Dlg(title="Participant Information")
dlg.addField("Participant Number:")
dlg.show()

if dlg.OK:
    participant_number = dlg.data[0]
else:
    print("User canceled, exiting...")
    core.quit()

# Load stimuli from stimuli.xlsx
stimuli_df = pd.read_excel("stimuli.xlsx")

# Define experiment phases and display durations
phases = [500, 750, 1000, 1250]

# Initialize PsychoPy window
win = visual.Window(size=(800, 600), fullscr=False, color="white")

# Initialize text stimulus
text_stim = visual.TextStim(win, text="", height=30)

# Initialize data storage
output_data = []

# Loop through each phase
for phase_num, duration in enumerate(phases, start=1):
    for word in stimuli_df["Word"]:
        # Display stimuli word
        text_stim.text = word
        text_stim.draw()
        win.flip()

        # Record onset time using core.Clock
        trial_clock = core.Clock()
        trial_clock.reset()

        core.wait(duration / 1000)  # Convert duration to seconds

        # Display prompt and collect participant response
        text_stim.text = "Please type the word you just saw. When you have finished, press ENTER."
        text_stim.draw()
        win.flip()

        # Record response time
        response_clock = core.Clock()
        response_clock.reset()

        response = event.getText()
        response_time = response_clock.getTime()

        # Append data to output
        output_data.append({"Phase": phase_num, "Word": word, "Response": response, "ResponseTime": response_time})

# Save data to output text file
output_df = pd.DataFrame(output_data)
output_df.to_csv(f"participant_{participant_number}_output.csv", index=False)

# Close PsychoPy window
win.close()

已排查项 #

• 系统内存充足
• 显卡驱动已更新至最新
• 实验所用字体已正确安装

解决方案建议 #

• 指定明确字体：初始化TextStim时指定系统确认真实存在的字体，例如visual.TextStim(win, text="", height=30, font="Arial")，避免自动选字体时的兼容问题。
• 重构TextStim实例：每次显示不同文本时，重新创建TextStim对象，而非修改已有实例的text属性。示例：

  # 替换循环内的text_stim.text赋值为：
  text_stim = visual.TextStim(win, text=word, height=30, font="Arial")
  

• 切换渲染后端：初始化Window时指定使用pygame后端，例如visual.Window(size=(800, 600), fullscr=False, color="white", winType='pygame')。
• 检查刺激文本：确认stimuli.xlsx中的单词无特殊字符、空值或不可渲染字符（如控制字符）。
• 更换PsychoPy版本：尝试切换到2023.1.x或2024.x版本，避开当前版本的pyglet兼容bug。
