import Metashape error

[arafat]

I upgraded to metashape 1.8.3. I am using the python wheel for Linux.

When I import Metashape I get:

Code: [Select]

ImportError: /usr/lib/x86_64-linux-gnu/libhogweed.so.4: undefined symbol: __gmpn_cnd_sub_n
any idea??

Hello arafat,

Can you please specify with OS distribution you are using?

Also please check, if removing the following file from Metashape installation folder helps to avoid the problem: lib/libgmp.so.10

I'm using nvidia/cuda:10.1-base in Docker (https://hub.docker.com/layers/cuda/nvidia/cuda/10.1-base/images/sha256-c5c4512afe0179cd018591348173a1344930f695fb23f8485a9b713efc9d87dc?context=explore)

1.8.2 works fine, but the new 1.8.3 does not.

if I delete libgmp.so.10 I still have the same error

Hello arafat,

Can you please check, if it helps then to remove libgmp.so.10 from the following directory contents: /usr/local/lib/python3.6/dist-packages/Metashape/

[arafat]

after deleting it I get

Code: [Select]

>>> import Metashape
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/Metashape/__init__.py", line 3, in <module>
    from .Metashape import *
ImportError: /usr/local/lib/python3.6/dist-packages/Metashape/Metashape.so: undefined symbol: curl_multi_poll

[arafat]

Thank you for your time.

Apparently, Its the curl being old curl 7.58.0 in nvidia/cuda:10-base

I have just finished testing, Installing new curl version didn't work. However, changing the OS to nvidia/cuda:11.6.1-base-ubuntu20.04 and upgrading the curl to curl 7.68.0 works after deleting libgmp.so.10

Best Regards,
