五、ImportError: cannot import name 'clock' from 'time' (unknown location)
六、UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x00000200EDD9BEA0>
1. OSError: [WinError 127] The specified program cannot be found. Error loading "D:\my_ruanjian\conda-myenvs\deeplearning\lib\site-packages\torch\lib\caffe2_detectron_ops.dll" or one of its dependencies.
Error reported:
Reason: It is caused by the mismatch between the versions of torch and torchaudio
Solution:
二、proj.db contains DATABASE.LAYOUT.VERSION.MINOR = 0 whereas a number >= 2 is expected. It comes from another PROJ installation
Scenario: A problem was discovered recently. When developing usingGDAL+Python, the code always reports the following error:
Reason: It can be seen from the error that GDAL encountered a version conflict when calling PROJ.
- The bottom layer of GDAL uses the PROJ library to perform coordinate system-related conversions;
- The PostgreSQL database plug-in PostGIS also uses PROJ;
The PROJ library versions installed by the two tools are different and interfere with each other in the computer environment variables.
Solution: Find the installation address corresponding to your own python package,
import os
# 对应自己的python包的安装地址
os.environ['PROJ_LIB'] = r'D:\my\python-pycharm\python-envs\pathplanning\Lib\site-packages\pyproj\proj_dir\share\proj'Then when I run the code, no error is reported.
三、 There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.tuna.tsinghua.edu.cn', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: EE certificate key too weak (_ssl.c:1002)'))) - skipping
Error: An error is reported when using pip install a certain package
Cause analysis: Unable to access https://pypi.tuna.tsinghua.edu.cn/simple/pip, SSL certificate authentication problem.
Solution: At this time, you need to obtain ssl certificate certification. You need to add: -i http:// after the original installation command. mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com (you can also change to other sources), this isAli source - -trusted-host mirrors.aliyun.com This is to obtain the authentication of the ssl certificate.
四、Max retries exceeded with url: /pkgs/main/linux-64/current_repodata.json (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: EE certificate key too weak (_ssl.c:1002)')))
Error: After I set up the domestic source, I used conda to create a virtual environment, and the following error occurred when downloading the python version.
Cause analysis: Judging from the error message, the resource cannot be obtainedhttps://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64/current_repodata.json, and then try to obtain the resource through the wget command
Solution: Enterconda config --set ssl_verify false in the command line to modify the settings, or add a line at the end of the file~/.condarc ( If necessary, just modify it), change the https in the Tsinghua source links to http. ssl_verify: false
五、ImportError: cannot import name 'clock' from 'time' (unknown location)
Error reported:
Reason: This problem usually occurs after Python 3.8, because in Python 3.8, the clock() function in the time module is abandoned and replaced by the perf_counter() function and process_time() function.
Solution: Then, the way to solve this problem is to use the perf_counter() function or process_time() function instead of the clock() function. These two functions are used for performance counting and process timing respectively, which can measure time more accurately.
from time import process_time as timer
timer()
六、UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x00000200EDD9BEA0>
Error reported:
Reason: This link is a picture, but python cannot read the picture and reports an error. There may be a problem with the picture that prevents it from being read.
