Mac執行tensorflow發生RuntimeError: dictionary changed size during iteration

問題：
Homebrew的python3版本是3.7.3
在執行tensorflow時出現以下

.
.
.
File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/linecache.py", line 48, in getlines
    for mod in sys.modules.values():

RuntimeError: dictionary changed size during iteration

解決：
$ sudo vi /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/linecache.py

第48行改成
for mod in list(sys.modules.values()): # for mod in sys.modules.values():
