Hi, could you paste a code snippet that can reproduce this bug?

Though from the error message, it looks like you're using cb with threading, which is not supported for now.

Since I don't get more information, I'll use my best judgement to close this issue, cause it's most likely to be expected due to the reason mentioned above. But feel free to comment if it's not.

python 3.7.0
Cyberbrain 0.1.4
Windows 10
Similar problem in the Terminal, the graph shows up though.

The test code is here.

import struct
import time
from cyberbrain import trace

@trace
def test():
    a = b'\x00\x00'*4096
    start = time.time()
    ans = [0]*(len(a)//2)
    for i in range(0, len(a)//2):
        ans[i] = int.from_bytes(a[(i*2):(i*2+2)], byteorder='little')
    length = len(ans)
    data = struct.pack(str(length)+'H', *ans)
    stop = time.time()
    print(stop-start)

if __name__ == '__main__':
    test()

Hi @joezhouchenye, I tried to run your code on Python 3.7.9 + Win 10, and can't reproduce this error. Could you try using the latest version of Python 3.7 and see if the error still exists?

[joezhouchenye]

It seems that there are some setting problems. I freshly installed python3.7.0 and VS Code on another computer and there is no error. I cannot figure out why yet.

Sounds good, glad you got it working.
