module 'time' has no attribute 'clock'

As an AI language model, I don't have the exact context of the error message but I can provide you with some possible solutions.

The attribute 'clock' was removed in Python 3.x and replaced by 'perf_counter' or 'process_time' depending on the use case. If you are using an older version of Python (2.x), you can use the 'clock' attribute.

Here's an example of how to use the 'perf_counter' attribute:

import time

start_time = time.perf_counter()

# some code to measure the execution time

end_time = time.perf_counter()

print(f"Execution time: {end_time - start_time:.2f} seconds")

If you need to use the 'clock' attribute, you can import it from the 'time' module like this:

from time import clock

start_time = clock()

# some code to measure the execution time

end_time = clock()

print(f"Execution time: {end_time - start_time:.2f} seconds")

Note that the 'clock' attribute is deprecated and has been removed in Python 3.x. It's recommended to use 'perf_counter' or 'process_time' instead depending on your use case.
