start = time.clock() AttributeError: module 'time' has no attribute 'clock' 出现报错

这个报错是因为在Python 3.8版本中,time模块的clock()函数已经被移除了。取而代之的是使用time.perf_counter()或者time.process_time()函数来计算时间。你可以将代码中的time.clock()替换为time.perf_counter()或者time.process_time()来解决这个问题。

AttributeError: module time has no attribute clock
The error message "AttributeError: module time has no attribute clock" means that the "clock" attribute is not available in the "time" module.
The "clock" function was deprecated in Python 3.3 and removed in Python 3.8. Instead of using "time.clock()", you can use "time.perf_counter()" or "time.process_time()" depending on your use case.
Here's an example of using "time.perf_counter()" to measure the time taken for a piece of code to execute:
```
import time
start_time = time.perf_counter()
# Code to be timed
for i in range(1000000):
pass
end_time = time.perf_counter()
elapsed_time = end_time - start_time
print(f"Elapsed time: {elapsed_time:.6f} seconds")
```
AttributeError: module 'time' has no attribute 'clock'怎么解决
在Python 3.8中,time模块已经移除了clock()方法。如果你在使用clock()方法时遇到了AttributeError: module 'time' has no attribute 'clock'的错误,可以考虑使用time.perf_counter()或time.process_time()方法来替代。
1. 使用time.perf_counter()方法:
```python
import time
start_time = time.perf_counter()
# 在这里执行你的代码
end_time = time.perf_counter()
execution_time = end_time - start_time
print("执行时间:", execution_time)
```
2. 使用time.process_time()方法:
```python
import time
start_time = time.process_time()
# 在这里执行你的代码
end_time = time.process_time()
execution_time = end_time - start_time
print("执行时间:", execution_time)
```
这两种方法都可以用来计算代码的执行时间,根据你的需求选择其中一种即可。
