我正在尝试在Google colab上运行包含以下代码的bash文件“ run.sh”：
pip uninstall tensorflow
pip install tensorflow=={1.14}
wget -P weights https://pjreddie.com/media/files/yolov3.weights
python detect.py $1
运行此操作会引发以下错误：
ERROR: Could not find a version that satisfies the requirement tensorflow=={1.2} (from versions: 0.12.1, 1.0.0, 1.0.1, 1.1.0rc0, 1.1.0rc1, 1.1.0rc2, 1.1.0, 1.2.0rc0, 1.2.0rc1, 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.4.1, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0, 1.7.1, 1.8.0rc0, 1.8.0rc1, 1.8.0, 1.9.0rc0, 1.9.0rc1, 1.9.0rc2, 1.9.0, 1.10.0rc0, 1.10.0rc1, 1.10.0, 1.10.1, 1.11.0rc0, 1.11.0rc1, 1.11.0rc2, 1.11.0, 1.12.0rc0, 1.12.0rc1, 1.12.0rc2, 1.12.0, 1.12.2, 1.12.3, 1.13.0rc0, 1.13.0rc1, 1.13.0rc2, 1.13.1, 1.13.2, 1.14.0rc0, 1.14.0rc1, 1.14.0, 1.15.0rc0, 1.15.0rc1, 1.15.0rc2, 1.15.0rc3, 1.15.0, 1.15.2, 1.15.3, 2.0.0a0, 2.0.0b0, 2.0.0b1, 2.0.0rc0, 2.0.0rc1, 2.0.0rc2, 2.0.0, 2.0.1, 2.0.2, 2.1.0rc0, 2.1.0rc1, 2.1.0rc2, 2.1.0, 2.1.1, 2.2.0rc0, 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.3.0rc0, 2.3.0rc1, 2.3.0rc2)
ERROR: No matching distribution found for tensorflow=={1.2}
但是，在google colab单元格中运行以下代码就可以了。
!pip uninstall tensorflow
!pip install tensorflow=={1.14}
有什么想法吗？

请勿在版本import time
list = [1,2,3,4,2323449,1,525]
def Search(arr):
# sorting
i = 0
print(f"Given list: {list}")
print("Sorting...")
time.sleep(1.75)
for i in range(len(list)):
if i + 1 >= len(list):
break
elif list[i + 1] < list[i]:
list.sort()
print("List has been sorted ")
print(f"Sorted list: {list}")
#---------------------------------------
# searching
inputCheck = True
while inputCheck:
n = input("Enter a number to find in the list: ")
try:
n=int(n) # if input is valid value then seaching will be done so store that number
inputCheck = False
except ValueError or TypeError:
print("Please enter a number")
time.sleep(0.6)
print("Searching...")
l = 0
h = len(list) - 1
while l <= h:
mid = (l + h) // 2
if list[mid] == n:
pos = mid
print(f"Found at index {pos}")
break
else:
print(n)
if list[mid] < n:
l = mid+1 # as index mid has already checked so set l=mid+1
else:
h = mid-1 # mid has already checked so set h=mid-1
Search(list)
前后使用花括号（{1.14}）。只需tensorflow作为版本号即可完成工作。
